Thermal Overload Relays (TOR)
DESCRIPTION
Motor protection for overload and phase failure
Thermal overload relays are economic electromechanical protection devices for the main circuit. In combination with contactors, they provide reliable protection against overloads and phase failures for motors. They allow to set up customized motor starting solutions according to individual needs.
Main Benefits
- Reliable protection for motors in the event of overload or phase failure
- Easy creation of individual motor starting solutions
- Perfect fit to ABB’s contactors: directly mounted and connected without further wiring
- Single mounting kits and accessories for remote control available for specific applications
- Selectable automatic reset mode allows to reduce downtimes and travelling costs
- In combination with ABB mini contactors, the installation in narrow spaces is possible
- Rated for AC and DC loads
Main Features
- Trip class 10/10A
- Adjustable current setting ranges
- Overload protection with phase loss sensitivity
- Temperature compensation up to +70°C
- Selection between automatic or manual reset mode
- Stop and test function
- Finger safe housing (IP20)
- Large markings on setting scale for precise setting
- Suitable for 1-phase applications

ABB OPR
During a storm, when propagation field conditions are favorable, an OPR ESE air terminal will generate an upward leader. This upward leader from the OPR tip propagates towards the downward leader from the cloud.
The emission of an early streamer to a lightning event delivers a beneficial triggering time compared to a single rod air terminal exposed to the same conditions. This in turn drives the enhanced performance and protective distance achievable by ESE devices.
The beneficial triggering time is determined as the average time gained at the moment of sparkover, with efficiency confirmed by high-voltage laboratory testing. All ESE tests are defined in Annex C of the French standard NF C 17-102 (2011 Version).
This beneficial triggering makes OPR air terminals especially effective for the protection of industrial sites, administrative or public buildings, monuments and open-air sites such as sports grounds. -
ABB Motor Starter
Manual motor starters, also known as motor protection circuit breakers (MPCBs) or manual motor protectors (MMPs), are electromechanical protection devices for the main circuit. They are mainly used to switch motors ON/OFF manually and to provide fuseless protection against short-circuit, overload and phase failures. Fuseless protection saves costs, space and ensures a quick reaction under short-circuit condition by switching the motor off within milliseconds. Starter combinations are setup together with contactors and are available with screw or Push-in Spring terminals.

ABB TMAX XT
The SACE Tmax XT series of Moulded Case Circuit Breakers (MCCBs) are designed to maximize ease of use, integration and connectivity while reliably delivering safety and quality. Rather than just offering standalone protection, they are seen as key elements of the system that give you complete flexibility, extreme breaking capabilities and reliable performance under pressure. With seven different sizes and protection features of up to 1600A there’s a solution for every purpose.
Tmax XT moulded case circuit breakers guarantee an extremely high performance level while being progressively smaller in size, simple to install and able to provide increasingly better safety. Range is complete with four frame sizes: XT1, XT2 up to 160A and XT3, XT4 up to 250A. -
ABB MCB
Miniature circuit breakers (MCBs) ensure electrical safety in homes, offices and other buildings as well as for industrial applications by protecting electrical installations against overloads and short circuits. Once a fault is detected, the miniature circuit breaker automatically switches off the electrical circuit to prevent damage to wires and to avoid the risk of fire. Warranting reliability and safety for people and assets, MCBs are equipped with two tripping mechanisms: the delayed thermal tripping mechanism for overload protection and the magnetic tripping mechanism for short circuit protection.
