Description
TeSys Deca Overload Relays
TeSys Deca TeSys Deca is a flexible range of thermal overload relays for motors from 0.06 kW to 75 kW. Coordinated with TeSys Deca contactors, they can be fitted directly onto the contactors for compactness, or apart using accessories.
Easy Selection
Adjustment range makes new relays a natural choice for a wide range of applications, from 0.1A to 110A.
Simple to install
Self-powering eliminates the need for an external power supply. Can be combined with TeSys Deca contactors to form an extremely optimised starter.
Efficiency
Close-couple configuration for reduced installation time and selectable trip class (5, 10, 20, 30) allows you to set the desired level of protection.

Motor Safety and Control with TeSys Deca
TeSys Deca overload relays are widely used across industries, infrastructure, and buildings to provide reliable protection against motor overload and phase loss.
They serve as the ideal complement to magnetic-only circuit breakers by managing thermal protection for motors. Additionally, they offer selectable tripping options—manual, remote, or automatic reset—for enhanced process management and operational flexibility.
