The MPU-32-01-01 is a motor protection unit with a supply voltage between 65–265 V ac and 80–275 V dc. This unit provides current and temperature-based protection with communication via RS/TIA-232-RS/TIA-485.

The SE-100T is a ground-fault-relay test unit designed to test the current pickup level of ground-fault protection. The tester injects current through the window of installed ground-fault current transformers to verify the operation of ground-fault monitors and relays. It is used on substations, motor control centers (MCCs), central distribution panels, switchboards, and test benches to verify relay operation. The SE-100T tests the entire ground-fault circuit including current transformers, wiring, ground-fault relay and the operation of the interrupting device. It is recommended to test every relay and its current interrupting device annually.

The SE-105/SE-107 is a combination ground-wire monitor and ground-fault relay for resistance-grounded systems. It continuously monitors the integrity of the ground conductor to protect portable equipment from hazardous voltages caused by ground faults. The SE-105/SE-107 is an excellent choice for trailing cables 5 kV and under in underground mining applications. For higher voltages or long-cable applications, see the SE-134C/SE-135.

Used when replacing the GE Multilin 169, 269, or 369.

Used to panel mount the SE-601 and SE-701.

Reverse Power Relay. 100/110V L-L 1A. Protects the generator from being run as a motor. The Reverse Power Relay T2000 will protect the generator from being run as an electric motor. The T2000 will protect the prime mover of the generator against physical damage, but will also protect the parallel running generators from overload caused by the inversed load shift in a reverse power situation. T2000 reverse power relay function: The T2000 measures the current through an external 5A CT attached on phase L1. The phase angle (phi) is determined from the voltage measurement across L1 and L2. The T2000 calculates the active current as I x cos phi. If the active current becomes negative and exceeds the preset level (2 – 20 percent), the pick-up LED will activate and the trip delay timer (2 – 20 seconds) will also activate. The built-in trip relay will energize after the delay has passed, provided that the preset trip level was continuously exceeded during the time of the delay.

SE-330-21-00 is an advanced ground-fault and neutral-grounding resistor monitor with a supply voltage ac of 28–52 and a supply voltage dc of 36–72. Network communications is offered via USB; DeviceNet.

Overcurrent Relay230V5A Latching output. The T2200 has a broad application where all 3 phases or any single phase current detection will function for protection, control or monitoring. The relay detects the highest of the 3 input currents and, on exceeding the preset value, an output relay will be activated after a preset time delay. Available in many versions, varying in supply voltage, measuring currents, and functions.

Dual Overcurrent Relay400/450V 5A. The T2400 consists of two combined over current relays, intended for protection, or monitoring of generators, power transmissions and consumer supply. A typical application for protection of a generator is for one of the over current functions to trip the generator breaker and the other over current function to trip a nonessential service. Both over current functions could be used to trip 2 levels of nonessential load. The relay detects the highest of the 3 input currents and, on exceeding the preset values, output relays will be activated after preset time delays.
