Stel 63A MCB Change Over Breaker-Manual Transfer Switch

Stel 63A MCB Change Over Breaker is a manual transfer switch designed to safely and securely switch a single electrical load between two different power sources. Ideal for residential, commercial, and industrial applications, this device provides a reliable solution for managing backup power from a generator, solar inverter, or a secondary utility line. Its robust construction and user-friendly design make it an essential component for any system requiring a reliable power transfer mechanism.

Features
Manual Transfer Operation: The breaker features a manual three-position handle (Source 1, OFF, Source 2) that allows a user to physically switch the power supply. This ensures that the two power sources can never be connected simultaneously, preventing short circuits and equipment damage.
Integrated MCB Functionality: Unlike standard transfer switches, this device combines the functionality of a Miniature Circuit Breaker (MCB). It provides protection against short circuits and overloads for both power sources, offering a higher level of safety and convenience in a single unit.
High Current Rating: Rated at 63 Amps, this change-over breaker is capable of handling the high current demands of most household and small-to-medium commercial installations.
Durable Construction: The casing is made from high-quality, flame-retardant plastic, ensuring safety and durability. The internal components are designed for long-lasting performance and reliable switching under load.
Easy Installation: Designed for standard DIN rail mounting, this breaker can be easily integrated into existing consumer units or distribution boards, making for a straightforward installation process.
Clear Indication: The handle’s positions are clearly marked, providing a visual indication of which power source is active.
