ABB Thermal Overload Relay Direct Mount 3-Pole 10-13A Adjustable Current Range 2.2W Power TF42 1SAZ721201R1045 TF42-13

ABB TF42 thermal overload relay model 1SAZ721201R1045 TF42-13 is engineered for reliable protection of electric motors by shutting off power upon detecting overcurrent or phase imbalance, helping prevent motor damage and downtime. It mounts directly onto contactors and features a robust 3-pole configuration, accommodating both three-phase and single-phase systems with rated full load currents of 10A to 13A and a power dissipation of 2.2W.

The relay offers versatile reset options including automatic and manual modes, facilitating quick system restore post fault correction. Housed in a compact body measuring 45mm width, 70.5mm depth, and 88.3mm length, it fits well in constrained panel spaces. The screw-type terminals enable straightforward and secure wiring without requiring special tools.

Designed to operate reliably within harsh ambient conditions from -25°C to +60°C, this relay ensures consistent performance. The contact voltage rating of 690V AC/DC and IP20 enclosure class provide safe operation in typical industrial environments. Two auxiliary contacts further allow integration with control circuits for signaling purposes.

ABB TF42 relay complies with a broad spectrum of international standards such as IEC/EN 60947 series, UL 508, CSA, CE marking, RoHS directive, and others, assuring industrial safety and regulatory conformity.
