Overview
The Airpax UPL1-1R01-262-2 is a single-pole hydraulic-magnetic circuit breaker engineered for reliable circuit protection in specialized applications. Manufactured by Sensata Technologies (Airpax brand), this unit delivers precise overcurrent protection using a hydraulic-magnetic trip mechanism that compensates for temperature variations and minimizes nuisance tripping.
Key Features
- Hydraulic-magnetic protection principle for accurate current sensing
- Single-pole configuration with manual on/off switching
- Temperature-compensated operation eliminates false trips in varying environments
- Rated 0.25A at 250V AC with 10,000 AIC interrupting capacity
- Auxiliary switch contacts rated 5A @ 250V AC or 10A @ 120V AC
- Compact design suitable for panel and equipment mounting
Technical Specifications
The UPL1-1R01-262-2 combines precision protection with field-proven reliability. Wire gauge compatibility ranges from 1 to 5 AWG, accommodating standard industrial wiring requirements. The hydraulic-magnetic trip element responds proportionally to overcurrent without delay at normal operating levels, then trips rapidly during fault conditions.
Typical Applications
The Airpax UPL1-1R01-262-2 is intended for use in:
- Broadcast and communications equipment
- Data processing and control systems
- Vending and amusement machine protection
- Military and marine electrical systems
- Precision instrumentation requiring nuisance-trip-free operation
Compatibility & Replacements
Compatible With
- Standard DIN-rail and panel-mount enclosures rated for single-pole breakers
- Control circuits and auxiliary relay systems up to 10A @ 120V AC
- Industrial electrical systems requiring precise overcurrent detection
- Legacy aviation, military, and marine power distribution networks
Replaces / Drop-In Replacement For
Verify compatibility with your original equipment manufacturer or system integrator before ordering. The UPL1-1R01-262-2 is a legacy Airpax product; Sensata currently recommends the IAG series for new designs.
Works With
- Sensata / Airpax control and instrumentation ecosystems
