Circuit Breakers Model

EATON CIRCUIT BREAKERS E2 MINING MOLDED CASE

FEATURES

MSHA Trailing Cable Protection
Specifically designed for mining applications to protect all sizes of trailing cable as defined by MSHA 30 CFR 75 with minimum inventory requirements.
Superior Safety Trip Technology
Available with electronic trip units (e.g., 310+) that clear faults "faster than instantaneous" via the Arcflash Reduction Maintenance System (ARMS) for increased worker safety during maintenance.
Built-in Safety Monitoring
Equipped with an Undervoltage Release (UVR) and an LED indicator to ensure the breaker cannot be reset without proper power, adding a layer of operator safety.

SPECIFICATIONS

Voltage Rating: Up to 1,000 VAC (some versions up to 1,200 VAC)
Amperage Range: 3 A – 2,000 A depending on frame size
Frame Sizes: 7 frame sizes available
Trip Options: Instantaneous, Long/Short/Instantaneous, LSI (Long/Short/Instantaneous), with electronic trip units (310+ series)
Safety Standard: Compliant with MSHA (Mine Safety and Health Administration) 30 CFR 75 regulation for trailing cable protection
Ambient Temperature Rating: Typically rated for 40 °C; depends on specific trip unit or frame.

EATON CIRCUIT BREAKERS DS/DSII

FEATURES

Fully interchangeable platform
DS and DSII breakers share the same physical footprint and can be swapped in compartments with the same dimensions and ratings.
Zone‑selective interlocking (ZSI)
Allows fast, coordinated tripping without intentional time delays, improving system selectivity and safety.
High short-time capability
Breakers rated above 240 VAC have a short-time rating equal to the instantaneous rating, enabling the breaker closest to a fault to trip first.

SPECIFICATIONS

Max Voltage Rating: 600 VAC
Continuous Current Frame Sizes: Available from 800 A through 5000 A (covered by three physical frame sizes).
Interrupting Capacity (Max): Up to 200 kA short-circuit capacity (optional, standard is 100 kA).
Rating: Typically 100% rated and UL listed.
Tripping System: Microprocessor-based Digitrip RMS Trip Units (models 510, 610, 810, 910) for protection functions (LSIG).
Design: Low-voltage power air circuit breaker (Magnum DS family).
