Leaks Are Dangerous
EL731 ac/dc sensitive earth-leakage relay can detect ground currents in resistance-grounded electrical systems down to 0 Hz to protect variable-frequency drives (VFDs) that operate at low speeds, during which ac current approaches dc. VFDs operating in resistance-grounded electrical systems are growing in popularity because of their ability to reduce arc-flash hazards.

Safe on Its Own
SafetyBridge product technology distributes safe I/O modules in a network without a fail-safe controller because the modules process the safety function themselves; the standard control system and network are used only as a transport medium. Safeconf software lets users parameterize the safety input and output channels and generate the safety logic, even without programming experience.

Safe Racking
Remote Racking System (RRS) promotes workplace safety by automatically racking circuit breakers from a distance via a remote control station and customized cord length. An RRS removes the operator from manual contact with the circuit breaker while it is being inserted or removed, an activity during which a significant percentage of arcing faults occur.

Time to Go
TD-CSR time delay control switch relay provides a means to mitigate arc flash danger in local circuit breaker operation by allowing a manually initiated, time-delayed trip or close. A flashing LED notifies the operator of pending trip or close operation and as a warning to evacuate the arc flash area. To avoid an inadvertent operation, the control pushbuttons must be depressed for four continuous seconds to activate the 10-second delay.
