Honeywell 51307039-100 Circuit Breaker Box Assembly
The Honeywell 51307039-100, also cataloged as the 51307039-100 Circuit Breaker Box Assembly, operates as a dedicated hardware component for power input distribution and circuit protection within Honeywell industrial control system cabinets. It routes primary dual AC feeds, provides two-way power extension capabilities, and controls line power isolation across internal system buses via two front-panel toggles.

Channel-to-Channel Isolation and Power Conditioning
Designed for installation inside process power control panels, the circuit breaker box maintains robust channel-to-channel isolation and physical signal separation between AC distribution buses and sensitive low-voltage DCS logic. The internal circuit protection topology suppresses inductive switching transients before they reach system power supply modules. High-voltage power feeds are fully isolated from surrounding signal conditioning components, supporting clean AC power distribution without degrading adjacent 4-20 mA HART loop protocol signals or fieldbus lines.
Frequently Asked Questions
Q: Does the 51307039-100 support dual voltage input ranges simultaneously?
A: The module is designed with dual-input circuitry rated for either 100-120 VAC or 220-240 VAC power feeds, supplying matching AC output levels up to a total current capacity of 10 A.
Q: How do the two integrated switches function on the assembly?
A: The switches provide direct physical disconnect capability for each primary AC input feed, allowing maintenance technicians to isolate specific power lines independently without disconnecting main supply cables.
Field Installation Guidelines
- Verify that incoming mains AC power feeds are fully de-energized and locked out prior to installing or servicing the assembly.
- Mount the 51307039-100 securely into its dedicated cabinet location using appropriate chassis mounting hardware to ensure physical earth grounding continuity.
- Terminate AC input and output power wiring according to terminal markings, maintaining correct line, neutral, and protective earth (PE) connections.
- Ensure all field AC wiring is routed separately from low-voltage instrument DC signal lines to prevent noise coupling.
- Verify that line fusing and load demands do not exceed the 10 A current rating before toggling the dual AC input switches to the ON position.
