Overview
The Siemens BQCH3B060 is a heavy-duty molded case circuit breaker designed for 480-volt, three-phase industrial and commercial power distribution systems. This bolt-on breaker delivers reliable short-circuit and overload protection with an instantaneous trip characteristic and triple-pole single-throw (3PST) contact configuration. Widely used in motor control panels, switchboards, and main distribution equipment, the BQCH3B060 meets rigorous industry standards for continuous duty operation.
Key Features
- 3-Pole Configuration – Handles 3-phase 480VAC systems with synchronized simultaneous switching
- 60-Amp Rating – Suitable for moderate to heavy industrial load protection
- Bolt-On Mounting – Direct frame mounting without require additional hardware; field-proven design
- 14kA AIC Rating – Short-circuit interrupting capacity at 480V for coordinated protection schemes
- Instantaneous Trip – Fast response to fault conditions; no intentional time delay on overload
- Thermal-Magnetic Operation – Combines thermal sensitivity for sustained overload detection with magnetic response for instantaneous short-circuit protection
Technical Specifications
The BQCH3B060 is engineered for demanding applications requiring reliable, repeatable electrical isolation and protection. All specifications are factory-verified and meet UL 489 and ANSI standards.
Typical Applications
- Three-phase motor control circuits and branch protection
- Main distribution and feeder protection in industrial panels
- Commercial HVAC and refrigeration systems
- Manufacturing equipment power distribution
- Data center and industrial UPS integration
- OEM switchgear and control panel integration
Compatibility & Replacements
The Siemens BQCH3B060 is part of the BQCH family of molded case breakers and is widely stocked by major industrial distributors. As a bolt-on frame breaker, it integrates with standard Siemens 480V busway systems and panels designed for BQCH-series devices. For applications requiring exact replacement of an existing BQCH3B060, verify mounting style, voltage, and AIC rating to ensure compatibility. Consult a qualified electrical professional or distributor for cross-reference guidance on alternate manufacturers or legacy equivalents.
