Residual Current Device Product Selection
The Bulletin 1492 Residual Current Devices are available in 2- or 4-pole construction with (4) sensitivity settings to detect earth leakage to EN/IEC standards. Bulletin 1492-RCDs are designed to provide a degree of safety⋆ in the sensing of earth leakage that can be hazardous to personnel or machinery. Both line and load terminals accept 1.5…35 mm2 copper wire.
⋆ It is recommended that the devices be tested monthly by using the “TEST” button to check for proper operation of the device.
