Overview
The Siemens ED63A010 is a 3-pole molded case circuit breaker (MCCB) from the Sentron Series, specifically engineered as a motor circuit protector (MCP). Operating at 600VAC/250VDC with a 10-amp current rating, this device provides instantaneous short-circuit protection while minimizing false trips during motor startup inrush conditions. The ED6 frame design delivers a compact, bolted-on mounting solution suitable for industrial motor control centers, automation panels, and switchgear installations.
Key Features
- Instantaneous Magnetic Trip: Provides immediate protection against hard short-circuits without thermal delay, ideal for motor circuit protection
- 18 kA Interrupt Rating at 600V: Handles high fault currents safely; 25 kA at 480V for extended compatibility
- Low Nuisance-Trip Design: Engineered to tolerate inrush current spikes typical of motor starting, reducing unwanted downtime
- Load Lug Terminals: Accepts copper 14–10 AWG or aluminum 12–10 AWG wire for flexible installation options
- UL 489 / IEC 60947-2 Certified: Meets industry standards for molded case circuit breakers and safety agency approvals
Technical Specifications
The ED63A010 combines robust electrical performance with a compact footprint. Magnetic trip range is adjustable from 30 to 100 amps, and motor FLA (full-load ampere) range is 2.3 to 9.1 amps, providing flexibility across a wide variety of motor applications. Standard ETI range design ensures reliable operation in demanding industrial environments.
Typical Applications
- Direct-online (DOL) or soft-starter motor circuits in pumps, fans, compressors, and conveyors
- Motor control centers (MCCs) and industrial control panels requiring 600V three-phase protection
- Legacy and retrofit installations where ITE Sentron compatibility is required
- Food processing, water treatment, manufacturing, and HVAC motor protection schemes
Compatibility & Replacements
The ED63A010 is a non-interchangeable type within the ED frame family. Direct substitutes must carry the same part number or equivalent ITE/Siemens Sentron MCP designations. If replacing an older ED-frame breaker, verify load lugs and terminal compatibility. Common alternatives in the ED6 series include higher-amperage ratings (ED63A016, ED63A020, etc.), but the 10A rating is non-substitutable with other frame sizes. For system integrators and maintenance technicians seeking exact replacements, confirm model and terminal style before ordering.
