MAGSET Magnetic Adjustment System for Relays & Breakers

MAGSET Series – MAGgnetic SETting System for Relays and Circuit Breakers

High-precision automatic magnetic adjustment solution for differential relays and circuit breakers, in R&D and production environments.

High-precision magnetic adjustment of differential relays and circuit breakers

Fully automated saturation, adjustment, and verification sequences

Fast, single-pass process for simultaneous desaturation and adjustment

Dual-fixture enabling high-throughput production

Product Description

The MAGSET Series is a test platform dedicated to the high-precision magnetic setting of differential circuits.

This solution is designed to meet the needs of electrical protection equipment manufacturers, both in laboratory environments (R&D, investigation, quality...) and in industrial production environments (in-line testing).

The solution ensures accurate calibration of tripping thresholds, a critical factor in guaranteeing electrical protection system performance, compliance, and safety.

Thanks to fully automated sequences, the MAGSET Series delivers high precision, repeatability, and fast cycle times. Its unique combined desaturation and adjustment process enables single-pass calibration, significantly reducing task time compared to traditional adjustment methods.

Available as a laboratory test bench (19” cabinet) or an industrial rack for production line integration, the system supports seamless deployment across R&D, quality control, and high-volume manufacturing.
