Frequency Sensing Relay
-
This relay is a frequency monitoring relay with four stages of adjustable frequency pick up & drop out points. Each frequency set point can be set for under or over frequency operation & has an independent time delay driving an output relay. An undervoltage lockout is used to disable the four frequency outputs when the voltage falls below a preset level. Each of the four setting stages has a rate of change of frequency (ROCOF) element with an independent time delay.

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.

Product
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.

Voltage Monitoring, Timer Delay-on -off, 4 Pole
MTDV4 Relay
-
Plug-in electronic voltage monitoring relay with optional delay-on and delay-off timer function and four change-over contacts. The delay time is adjustable with a lockable knob (either delay-on or delay-off, the other delay is fixed). The relay can also be supplied with fixed time delays (no knob). The pull-in voltage and drop-out voltage are both adjustable via internal screws. The relay can also be supplied with a fixed pull-in and drop-out voltage. Suitable for monitoring DC voltages.
