R-ISW & R-ISW-ANL AC Current Monitoring Relays with delay off
DIN rail mounted, circuit breaker sized housing designed to automatically switch on a secondary load when a primary load current is detected.
Two different primary load current inputs are available, terminals with a 16A rating or a 6.5mm diameter through hole for 30A circuits.
The R-ISW-ANL has a current set point of approximately 200mA & an off-delay of approximately 5 minutes.
The R-ISW-A is a programmable version, set point adjustable from 50mA to 200mA (default) & a selectable off-delay of 1 minute, 5 minutes (default) or disabled.
- Selectable trip point 50mA to 200mA (R-ISW-A)
- Selectable off delay time, 1 minute, 5 minutes or no delay (R-ISW-A)
- DIN rail mounted 17.5mm wide
