VAMP Ltd.’s Vamp 221 is a dual-sensing and multi-zone arc protection system for low and medium voltage electrical power safety applications. The system’s ability to trip in just seven milliseconds means that electrical arcs are stopped well before their full explosive potential is reached, according to the company. Vamp 221 uses light and current sensing information to provide faster and more efficient protection than standalone over-current relays or busbar differential schemes, Vamp says. The master 221 module comes with 3-phase current measurement, 50BF breaker failure protection stages, four normally open trip contacts and two alarm contacts. Vamp says it can be programmed to sense electric arc conditions using either simultaneous light and current data, or light sensor information only.
