Power relays aid single-pole switching of loads
E-T-A CIRCUIT BREAKERS PR60 and PR80 power relays are suitable for the commercial vehicle market. Model PR60 is a monostable relay containing one coil and one resting position. PR80 is a bistable relay containing two coils and two resting positions – it is switched ON through an impulse and remains in the ON position until it is switched off by an additional impulse. Both devices provide continuous loads up to 300A and current peaks up to 2400A – making the products suitable for single-pole switching of large loads in military, construction and agricultural equipment.
