The Wacker Neuson Circuit Breaker 30 Amp 12VDC is a genuine OEM component designed for the HI 770 XHD Indirect Air Heater series, including Arctic Bear XHD and Arctic Bear XHD NS configurations. As a direct OEM replacement, part is manufactured to the same specifications as the original, ensuring a straightforward swap with no guesswork. This circuit breaker fits across multiple HI 770 XHD build variants, making it the go-to solution whether you're servicing a single-outlet or dual-outlet heater configuration. Keep one on hand during cold-weather operations when heater uptime is critical.
Key Features
- Correct 30A/12VDC Rating — Matches the exact amperage and voltage spec of the original circuit breaker, ensuring the protection circuit functions as engineered for the HI 770 XHD heater's electrical system.
- Genuine Wacker Neuson OEM Part — Sourced directly through Wacker Neuson, this is the same component installed at the factory — not an adapted substitute.
- Drop-In Replacement — Designed to connect and mount in the same position as the original, so installation is straightforward for technicians already familiar with the HI 770 XHD platform.
- Broad HI 770 XHD Coverage — Compatible with Arctic Bear XHD, Arctic Bear XHD NS, and multiple HI770XHD build configurations, covering both 1x16, 1x20, and 2x12 outlet variants.
- Electrical Protection Restored — A faulty or tripped circuit breaker that won't reset leaves the heater inoperable; replacing it with the correct 5200011736 restores full overcurrent protection and gets the unit running again.
- Critical Safety Component — As the primary overcurrent protection device in the heater's 12VDC circuit, an correctly rated circuit breaker is essential to prevent wiring damage or fire risk under fault conditions.
A circuit breaker in an indirect air heater acts as the electrical safety valve for the unit's 12-volt DC system — it monitors current flow and automatically interrupts the circuit if a fault or overload occurs, protecting wiring and components from heat damage. On the HI 770 XHD, this 30-amp breaker safeguards the heater's control and ignition circuitry; if it trips and cannot be reset, or has failed open, the heater will not power on. Replacing a failed breaker with the correct OEM-rated unit restores both function and the protection the circuit was designed to have.
