* responds before arcs develop fully - minimizing electrical switchgear damage and downtime, and greatly reducing employee safety risks

Great Neck, New York - The protection relay manufacturer Vamp is launching a flexible multi-zone
arc-protection system onto the US market for low and medium voltage electrical power safety applications.
The system's ability to trip in just 7 milliseconds means that electrical arcs are stopped well before their
full explosive potential can be reached. This not only minimizes the damage and downtime that arcs can cause to electrical switchgear, but also avoids the need for much of the expensive and time consuming safety clothing and procedures that are currently used by many workers in these plant areas.

Designated 221, the new multi-zone system uses light and current sensing information to provide faster and more efficient protection than standalone over-current relays or busbar differential schemes. Combined with modular design, which allows the base unit to be expanded, the new system serves an extremely broad range of electrical switchgear protection requirements.

The master 221 module comes with 3-phase current measurement (and 2-phase and earth-fault current measurement), 50BF breaker failure protection stages, four normally open trip contacts, and two alarm contacts. It can be programmed to sense electric arc conditions using either simultaneous light and current data, or light sensor information only, and operates in just 7 milliseconds - less than a quarter of the time of traditional alternative technologies.

With four light zones available, the 221 unit offers a highly flexible arc protection solution that can accommodate a wide variety of equipment configurations, ranging from simple single-cabinet applications, to complex configurations with selective tripping of busbar, breaker and cable compartments.

Up to three different I/O units are available to extend the system's capability and configuration flexibility. The choice of expansion modules includes a 10-channel point sensor I/O unit, a I/O module which supports up to 76 yard of fiber cable light sensor in up to three loops, plus a separate over-current I/O unit that will expand the feeder monitoring capability of the overall system to up to 16.

The 221 comes with its own keypad, display and LED indicators, making it simple to program, as well as identify the location of any faults./ins
