Product Description

ABB TF42 Thermal Overload Relay model offers essential motor overload protection with a power rating of 2.6W and a flexible adjustable current range from 16 to 20 amperes. It is designed with 1 normally open and 1 normally closed contact to safeguard motors in industrial, manufacturing, and automation systems against overload and phase failure conditions.

This relay includes a trip class 10 for timely motor protection and features phase loss sensitivity to detect and respond to phase failures. The product operates reliably within a temperature range of -25°C to 60°C thanks to its temperature compensation capabilities. Users benefit from selectable automatic or manual reset functions, allowing flexible operation depending on application needs.

Included is a trip-free mechanism which ensures the device consistently interrupts the circuit under fault conditions to prevent motor damage. The relay offers clear status indication on its operational state, and its direct mounting design allows seamless integration with block contactors. Security is enhanced through sealable operating elements that deter tampering.

Ideal for inclusion in motor starter combinations used in electrical panels within industrial automation, manufacturing plants, and HVAC systems, the ABB TF42 relay is widely applicable for both indoor and outdoor installations. It meets multiple international standards including UL 508, IEC/EN 60947 series, and RoHS compliance.

Provides reliable overload and phase failure protection for motors. Adjustable current settings from 16 to 20 amperes to match motor specifications. Robust design suitable for varied industrial and commercial environments.

Complies with multiple global safety and performance standards. Seamless compatibility with AF range of contactors for integrated control solutions. Explore our range for more ABB Thermal Overload Relays and accessories, built for industrial and automation applications at EnvMart.
