ep 388 ep-relays high voltage and current cut-off capacity in a compact package 150a 2 form a 150a 1 form a 60a features ? control of large voltages and currents the relays have a sealed construction that is ?lled with a hydrogen gas com- pound, and use a permanent magnet to establish a magnetic path for the arc. this allows them to switch high-level dc volt- ages of up to 400v dc. ? compact size and light weight the capsule contact construction is ?lled with a gas that has excellent thermal dis- sipation and insulation characteristics. because of this we have been able to re- duce the contact gap to one tenth that of conventional relays, and produce a com- pact and light design. ? no arc space is required: size includ- ing arc space 1/9 (compared to con- ventional contactors) the arc is not exposed to the outside, therefore, no arc space is not required. ? safety construction the arc is not exposed, therefore, the contactor is explosion proof and intrinsi- cally safe. ? quiet: operation noise 1/4 (compared to conventional contactors). along with the above-mentioned miniatur- ization, the operation noise has been re- duced to 70db, and, in addition, the operation noise remains unchanged when a current of 1000a or more is inter- rupted. ? high contact reliability the contact part is hermetically sealed, hence the contact resistance remains sta- ble regardless of the ambient conditions. ? mounting direction is not speci?ed the weight of the movable parts is light, and also the restoring force is large, hence the contactor is relatively unaffect- ed by gravity. ? line-up of indicator types (150a type only) 1 form a and 1 form b types with indica- tors for detecting welding of the main con- tacts are available. ? 12 and 24v dc coil voltage types are available. ? screw terminal blocks for easy wir- ing. specifications contact notes: same speci?cations as the 12 v type. #1 condition: nominal switching 100cycles, each cut off 2,500a #2 conditions: varistor used for coil surge absorption. note: if a diode is used the life will be lower. type 150a type 60a type arrangement 1 form a, 2 form a 1 form a rating nominal switching capacity (resistive load) 150a 400v dc 150a 277v ac 60a 400v dc 60a 277v ac short term current 300a (10min)(harness wire: 40mm 2 ) 120a (15min)(harness wire: 15mm 2 ) max. cut-off current 2,500a 300v dc (3 cycles) #1 600a 300v dc (5 cycles) overload opening/closing rating 600a 400v dc (min. 1,000 cycles) 180a 400v dc (min. 100 cycles) #2 reverse cut-off current C200a 200v dc (min. 500 cycles) C60a 200v dc (min. 1,000 cycles) #2 contact voltage drop (max.) 0.1v (when current [is 150a per 1] contact set) 0.1v (when current [is 60a per 1] contact set) nominal operating power 35w (inrush, approx 0.1s) 5w ( stable ) max. 5w expected life (min. operations) mechanical 10 5 2 10 5 electrical 3 10 3 150a 400v dc (l/r & 1ms) 3 10 3 60a 400v dc (l/r & 1ms #2 )

(please treat the relay as a product with limited life and replace it when necessary.) in the event that the relay loses cut-off ability, there is a possibility that burning may spread to surrounding parts, so con- ?gure the layout so that the power is turned off within one second. 6. permeation life of internal gas this relay uses a hermetically encased contact (capsule contact) with gas inside. the gas has a permeation life that is af- fected by the temperature inside the cap- sule contact (ambient temperature + temperature rise due to ?ow of electrical current). for this reason, make sure the ambient operating temperature is be- tween C40 and 80 c C40 and +176 f , and the ambient storage temperature is be- tween C40 and 85 c C40 and +185 f . 7. the case is designed so that it will not come off with normal handling. if you remove the case, the relay will not function as intended, and its performance cannot be guaranteed.
ep 394 8. if the power is turned off and then immediately on after applying the rated voltage (current) continuously to the relay's coil and contact, the resistance of the coil will increase due to a rise in the coil temperature. this causes the pick-up voltage to rise, and possibly exceed the rated pick-up voltage. in these circumstances, take measures such as reducing the load current, lim- iting the duration of current ?ow, and applying a coil voltage higher than the rated operating voltage (quick start). 9. the coil must only be supplied with its rated voltage. the voltage waveform supplied to the coil should be rectan- gular. 10. take steps to ensure that voltages that exceed the maximum allowed volt- age for a coil are never continuously applied. 11. take steps to ensure that the rated voltage and current values for the con- tacts are never exceeded. 12. the rated control capacity and life are given as guides. the contact life is heavily in?uenced by the type of load and other related condi- tions, and these factors must be given due consideration when using the relay. 13. main contact ratings in the ratings apply to when there is a resistive load. 14. if you are using an inductive load (l load) such that l/r > 1 ms, add surge protection in parallel with the inductive load. if this is not done, the electrical life will decrease and cut-off failure may occur. 15. when using the 150 a type, mount it as far away as possible from amateur wireless transmitters or devices that may generate large surges. to prevent malfunctioning due to high emission levels, it may be neccessary to take measures for e.m.i., such as adding a line noise ?lter or an electromagnetic shield. 16. since coil current control is per- formed, a slight amount of superim- posed line noise may be generated in the input line system. if this noise must be removed, install a line noise ?lter. 17. be careful that foreign matter and oils do not stick to the main terminal part. it is likely to cause a terminal part to give off unusual heat. use the fol- lowing speci?cations for the harness bus bar that the relay connects to: ? 150a type: nominal cross sectional area: min. 38mm 2 . ? 60a type: nominal cross sectional area: min. 14mm 2 . 18. avoid excessive load applied to the terminal in case of installing such as a bus bar etc., because it might give bad in?uence to the opening and closing performance. ? m8 screw terminal (150a main terminal part) terminal pulling up strength ; max.100n per terminal the up-down rotation torque applied to the terminal ; max.15nm 19. for ac cut-off there is no contact polarity, but con?rm the electrical life using the actual load. in the case of dc cut-off the contacts have polarity, so take due care. 9/1/2000 all rights reserved, ? copyright matsushita electric works, ltd. go to online catalog
