The self-diagnostic feature operates continuously. When an internal fault is detected, the relay will attempt to resolve the fault. Failing which, a fault alarm will be generated and output contact will be activated.

• Flame Retardant material tested against UL94v-0 fire standards
• MTB ANSI 86 Lockout Relay
• Enhanced test trip function prevents accidental activation of the relay’s ‘Test Trip’ command

MTB or Mechanical Trip Button is a proprietary lockout feature that prevents an operator from re-energizing the circuit breaker before isolating the fault and resetting the MTB.

When activated, the MTB latches the output contacts and continues to indicate the presence of a fault until it is cleared, and the relay reset. All these are achieved without the need for an auxiliary power supply to the relay.

Reduces the time needed for fault tracing with up to 20 tripping events recorded. Parameters recorded include type and magnitude of fault, date and time stamping.

Up to 40 operation logs recording. Parameters include trip settings, communication settings, output contacts settings, normalize events, relay trips, test trips, reset trips, record clearings and reset hour runs.

Shows the relays’ total time of operation (in hours). Used for scheduled servicing and maintenance.

Expandable with programmable output contacts and RS485 to integrate with a building monitoring system.

Improved image quality with wide viewing angle, long-lasting durability, low power consumption, and high contrast ratio.

Protection Degree
