## Overview

This 100A automatic over-current DC circuit breaker combines a resettable fuse and On/Off switch, supporting 12V to 48V DC systems. Engineered with UL94V-0 thermal plastic, it withstands high temperatures and harsh conditions. Rated IP67 waterproof and ignition protected, it ensures reliable protection against over-current events, wiring faults, and short circuits. Ideal for solar, automotive, marine, and off-grid power setups, it offers manual isolation and reset capabilities for superior system control and safety.

## Description

This 100A circuit breaker combines the functions of a resettable 100A fuse and On/Off switch in one unit. It is ideal for any DC system that requires both over-current protection and manual isolation of the circuit. This product is suitable for a wide range of DC system voltages from 12V to 48V. Like any fuse, this circuit breaker is designed to protect the system from over-current as a result of high-power draw, short-circuits, wiring mistakes, equipment faults or any other high current event. The circuit breaker is resettable which makes it a superior alternative to fuses which require replacement when blown. Additionally, the breaker has a manual-break option which allows it to be used as an isolator On/Off switch for simple disconnection and reconnection of the system. The circuit breaker is made from strong thermal plastic engineered to withstand high temperatures (UL94V-0 rated). The breaker is also water resistant (IP67 rated) and ignition protected (meets international standards S.A.E. J1625, J1171, UL1500). This product is suitable for a wide range of DC applications including: - Connecting solar or wind charge controllers to batteries; - Between off-grid inverter DC input and batteries; - DC power distribution or charging circuits; - Other DC automotive and marine applications. Specifications: - Rating: 100A - Type: Thermal overcurrent protection device - Material: Thermal plastic (UL rated 94V-0) - Operating temperature: -32C to 82C - Storage temperature: -34C to 149C - Terminals size: M6 - Enclosure: IP67 - Size : 74 x 48 x 37 mm - Weight : 110g - Waterproof rating: IP67 - International standard ratings (S.A.E. J1625, J1171, UL1500) Please contact Photonic Universe if you have any questions about this product.
