This relay monitors the voltages on both sides of a circuit breaker and

determines the existence of proper phase angle and voltage before

allowing the breaker to close.

Product Features & Benefits

Basler’s retrofit relays provide direct “plug and play” replacements for many

obsolete electromechanical relay designs with no wiring changes.

Other Basler relays fit into the cutouts of older electromechanical relays with

no panel drilling or cutting required. Wiring changes are required and an

adapter plate may be needed.
