Product Description

The H7E-TB-B Thermal Breaker is a compact circuit protection device designed for precise temperature control in industrial applications. It features a single input and output channel, directly interfacing with up to four external modules via standard terminal connections. Operating within a voltage range of 12-240V DC/AC and a temperature tolerance of -40°C to +85°C, this breaker ensures reliable performance in harsh environments. Commonly used in manufacturing, energy, and automotive sectors, the H7E-TB-B Circuit Protection system offers rapid thermal response with a fixed current rating of 30A, safeguarding equipment like motors and HVAC systems from overloads. Its sealed housing provides IP67 protection, while a mechanical trip mechanism eliminates the need for external power. Key advantages include maintenance-free operation and a 100,000-cycle lifespan, though its non-adjustable trip threshold may require complementary sensors for complex thermal management scenarios.
