Overview

The ABB TF65-53 (SKU: TF65-53) from ABB Electrification is an economical electromechanical thermal overload relay designed for reliable main circuit protection of motors. This device offers essential protection against overload and phase failure, featuring a Trip Class 10 rating for precise operational response. Engineered for consistent performance, the TF65-53 includes temperature compensation according to IEC/EN 60947-4-1, ensuring operation across an ambient air temperature range of -40 to +70 °C (open, compensated). It is suitable for operation up to a maximum altitude of 2000 m and demonstrates resilience with shock resistance of 25g / 11 ms and vibration resistance of 5g / 3-150 Hz. Key protective features include a trip-free mechanism to prevent unintended resets during fault conditions and selectable automatic or manual reset options. The relay is equipped with a normally closed (NC) trip contact for immediate fault signaling and a normally open (NO) signal contact for monitoring. An integrated STOP function facilitates rapid motor shutdown. Electrical connection capabilities for the main circuit include compatibility with rigid conductors (1 or 2 x 2.5-16 mm² or 1 or 2 x 2.5-35 mm²), flexible conductors with ferrule (1 or 2 x 2.5-10 mm² or 1 or 2 x 2.5-35 mm²), and stranded conductors according to UL/CSA (1 x AWG 12-2 or 2 x AWG 12-6). The auxiliary circuit supports rigid conductors (1 or 2 x 0.75-4 mm²) and flexible conductors with ferrule (1 or 2 x 0.75-4 mm²). Mounting is flexible, allowing direct attachment to ABB block contactors or installation on a 35 mm DIN rail using an available single mounting kit. The housing provides IP20 protection, with main circuit terminals rated at IP10. The TF65-53 is designed for direct connection to block contactors, simplifying integration into motor control systems.

T2700.0020

Overload Relay. 400/450V L-L 5A. The T2700 Overload Relay will protect the generator from excessive active load. The T2700 is necessary to protect the prime mover and alternator against physical damage. The T2700 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 T2700 calculates the active current as I x cos phi. If the active current exceeds the preset level (0.02 – 2 x I), the pick-up LED will ignite and the trip delay timer (0.1 – 10 seconds) will 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. Dials on the front facia provide easy adjustment of both trip level and delay. The LED based pick-up indication is ideal for testing the unit. Simplicity is the key to trouble free installation and service, as simplicity plays a key role in reducing the Total Cost of Ownership (TCO) for the complete supply system.
