MERLIN GERIN 32570 Miniature Circuit Breaker
The MERLIN GERIN 32570 is a high-quality miniature circuit breaker (MCB) from the Merlin Gerin Multi9 series. Designed to protect electrical circuits from damage caused by overloads and short circuits, this MCB is suitable for residential, commercial, and industrial applications. It is known for its reliable performance, ease of installation, and long-term durability.
Technical Specifications
Product Type: Miniature circuit breaker (MCB)
Series: Merlin Gerin Multi9 series
Protection Functions: Overload protection, short-circuit protection
Tripping Mechanism: Thermal-magnetic trip unit
Mounting: DIN rail (35mm)
Applications: Residential electrical circuits, commercial buildings, industrial control panels, lighting circuits
Features: Reliable and efficient protection, easy installation and maintenance, compact design
Thermal-Magnetic Protection
The 32570 MCB incorporates a thermal-magnetic trip unit that provides comprehensive circuit protection. The thermal element uses a bimetallic strip that bends when heated by prolonged overcurrent, causing the breaker to trip after a time delay proportional to the overload magnitude. The magnetic element uses a solenoid that trips instantaneously when short-circuit currents occur, providing rapid fault clearing. This dual mechanism ensures both safe handling of temporary overloads and immediate response to dangerous short circuits.
Easy Installation and Versatility
Designed for DIN rail mounting, the 32570 MCB installs easily in standard electrical distribution boards and control panels. Its compact form factor allows high-density installation, saving valuable panel space. The Multi9 series is known for its robust construction and long service life, providing accurate and reliable protection for years. The breaker is suitable for protecting circuits in residential buildings, commercial facilities, and industrial equipment.
Application Domains
The MERLIN GERIN 32570 is used in residential electrical distribution panels for lighting and socket circuits, commercial building power distribution, industrial control panels for protecting control circuits and small machinery, and as a reliable replacement part for existing Multi9 series circuit breakers.
