Motor & Distribution Protection

Bulletin 193 IEC and 592 NEMA E1 Plus Electronic Overload Relays are accurate and reliable. They are durable, flexible to fit most applications, and easy to install. Through optional side-mount modules, you can expand communication and protection.

Bulletin 193/592 E300™ Electronic Overload Relays offer a flexible design, simplified wiring, and seamless Logix integration. Real-time diagnostics are transformed into actionable information which maximizes your up-time and protects your assets.

Our Bulletin 140M Motor Circuit Protectors may provide a disconnecting means for motor branch circuit, branch-circuit and short-circuit magnetic protection, and manual switching. These devices are rated from 0.16…45 A. In North America, electrical codes require that an individual motor branch circuit be protected by a UL/CSA Listed fuse, circuit breaker, or self-protected combination motor controller.

Our Bulletin 140M Motor Protection Circuit Breakers can provide a disconnecting means for motor branch circuit, branch-circuit and short-circuit magnetic protection, overload thermal protection, and manual switching. These devices are rated from 0.1…45 A.

Bulletin 140G Molded Case Circuit Breakers have nine different frame sizes with a range of 10…3000 A to accommodate your required current ratings and breaking capacities. With a wide range of operators and accessories, these circuit breakers provide the protection of circuits against overload, short circuit, and ground fault.

Bulletin 1492-SPM Supplementary Protectors are used to protect equipment in applications. They are current-limiting and feature dual terminals for wiring and bus bar flexibility. With a 40 ˚C (104 °F) calibration temperature, these protectors are suitable for extreme ambient conditions.

Our Rotary Disconnect Switches offer a variety of fused and non-fused versions from 20…1250 A and can be ordered with or without an enclosure. Non-fused styles permit use of your own fuse blocks. Fused switches, with integral fuse carriers, reduce panel space requirements.

Bulletin 4983-DS DIN Rail AC Surge Protective Devices are connected in parallel and use an MOV to clamp high-voltage surges. These devices are primarily used in the main electrical panel for the protection of 1- and 3-phase systems.

Bulletin 4983-DD DIN Rail Dataline Surge Protective Devices protect industrial communication networks. These devices use a combination of 3-electrode gas discharge tubes and fast-clamping diodes.

Bulletin 4983-DC DIN Rail Filter and Surge Protective Device is the combination of a filter and a surge protective device. This device provides transient and noise protection in one small package.

Bulletin 817S Thermistor Monitoring Relays offer state-of-the-art supplementary motor protective functions that you can easily add and apply to your motor control circuits.

Bulletin 814S Power Factor Monitoring Relays and Power (kW) Monitoring Relays offer state-of-the-art supplementary protective functions that you can easily add and apply to your motor control circuits.

Bulletin 813S Voltage Monitoring Relays offer state-of-the-art supplementary protective functions that you can easily add and apply to your motor control circuits.

Bulletin 809S Current Monitoring Relays offer state-of-the-art supplementary protective functions that are easily added and applied to your motor control circuits.

Bulletins 865 and 857 Motor and Feeder Protection protects devices in the distribution networks of utilities, industry, power plants and offshore application. Configure these relays using our bundled SetPointPS software.

Bulletin 857 Motor-Feeder Protection, Medium Voltage offers solutions for today’s motor and feeder protection requirements in one package. Our protection relay gives you flexible control to maximize your motor’s output capabilities, and provides current, voltage and motor protection functions. The protection relay can be integrated into a low voltage or medium voltage Motor Control Center, or can be purchased as an OEM component. Configure these relays using our bundled SetPointPS software.

Bulletin 193-T1 IEC Bimetallic Overload Relays are designed for use with Bulletin 100-C Contactors and Bulletin 104-C Reversing Contactors.

Bulletin 193-K IEC Miniature Bimetallic Overload Relays are designed for use with Bulletin 100-K Contactors and Bulletin 104-K Reversing Contactors. These thermal overload relays include a differential mechanism for sensitivity to phase-loss conditions.

Bulletin 193 IEC and 592 NEMA E3 and E3 Plus Electronic Overload Relays are optimal world-class products with a broad range of features in one complete, compact package. These multi-function, solid-state, microprocessor-based relays are designed to protect single- or three-phase squirrel cage induction motors. Our relays help you manage and monitor motor performance to prevent and minimize production downtime.

Our Bulletin 1692 Electronic Circuit Protection Modules protect the secondary circuits of 24V DC switched mode power supplies. These modules monitor both supply voltage and load currents, and you can monitor and control the modules both locally and remotely.
