Product Description

Pacer’s Type 1658 panel-mount thermal circuit breakers provide dependable overcurrent and short-circuit protection for marine and vehicle electrical systems. Rated for operation up to 50 VDC, these ignition-protected breakers are suitable for installation in enclosed compartments where potentially explosive gases may be present. Push-to-reset operation provides clear visual indication of a tripped circuit and allows for quick, convenient resetting. Available with screw or spade terminal connections, they offer flexible installation options. A compact design, nylon mounting bushing, included knurled nut and palnut, and durable stainless steel hardware make them a practical solution for space-constrained applications.
Characteristics:
- Push-to-reset allows for easy identification of a tripped breaker as well as an easy reset of the breaker to the on position.
- Multiple connection styles support spade terminal connections or screw/ring terminal connections, allowing flexibility of installation.
- Includes knurled nut & palnut for easy and clean panel mount.
- A compact footprint allows for installation areas where space is limited.
- Ignition-protected safe for installation in closed compartments with potential explosive gases.
Features:
- Protects electrical circuits from short-circuit events and overcurrent loads, preventing wire insulation overheating and subsequent destruction.
- Visual indication of the circuit opened with the push button protrusion is also used for resetting to on.
- Bulletproof construction: High-temperature materials for engine compartment applications and stainless self-locking hardware.
- Harsh environment design with stainless steel hardware, self-locking screws, and an optional sealing boot.
