Arc Flash Monitoring
Arc fault protection for the fast clearance of arcing faults on BUS bars & within metal clad switchgear & associated cable boxes. The arc is detected using an optical sensor & the signal input to a protection device which alsomonitors the load current on the system.

Safety Relay, 4 Contacts, 10A
D-BW
The D-relays series are designed for demanding industrial applications such as power utilities and petrochemical industries. The construction of the relay and choice of materials makes the D-relay suitable to withstand corrosive atmosphere, low and high temperatures and vibrating environments. No external retaining clip needed as integrated ‘snap-lock’ will hold relay into socket under all circumstances and mounting directions All relays are equipped with a LED and suppression diode.

Current Protection Relay
The main earth fault protection relays in distributions systems, power stations & large manufacturing / processing plants can fail to detect a high impedance break down to earth causing hazard to human life & potential damage to plant & equipment. In these & other situations demanding extra sensitive earth fault protection, using solid state techniques, can be applied to detect earth currents down to 0.5% of the CT nominal current.

Timer, Delay-Off, 4 Pole
TDE4N relay
Plug-in electronic industrial timer relay with four change-over contacts. When the relay is de energized there is a delay on drop-out without any auxiliary power supply. The delay time is adjustable with a lockable knob. The relay can also be supplied with a fixed time delay (no knob).The relay is equipped with a LED which indicates the presence of energizing voltage. Standard equipped with back EMF suppression. Optionally equipped with magnetic arc blow-out for high breaking capacity and long contact life.

Auto Reclose and Sync Check
Operating records for overhead power lines reveal that most faults are of a transient nature (e.g. lightning induced) & that service interruptions may be minimized by use of automatic reclosing of circuit breakers. An automatic reclosure of the circuit breaker, after the fault clears, provides improved service continuity & system stability. The 1B230 Series Reclose Relay provides for single or double shot automatic reclosing of circuit breakers, following interruption of supply due to a fault in the system.
