Impulse switch UC. 1 normally open contact potential-free 10A/250V AC, incandescent lamps 2000W. No standby loss. For panel mounting. 45mm long, 45mm wide, 18mm deep. The latest hybrid technology combines the advantages of wear-free electronic control with the high power of special relays. Either universal control voltage 8..230V UC at control input +A1/-A2 or 230V with up to 5mA glow lamp current at the control input with glow lamp symbol (L)/-A2(N). The simultaneous use of two potentials at the control inputs is not permitted. Very low switching noise. No constant power supply required, therefore no standby loss. By using a bistable relay, there is no coil power loss and no heating thereby even when the relay is switched on. The relay contact can be open or closed during commissioning and synchronizes itself during the first operation. If this surge current switch is in a circuit that is monitored with a field isolator FR12-230V, it does not require an additional base load, but the m
