SCHENEIDER MCCB
The Schneider Electric MCCB (Molded Case Circuit Breaker) is a heavy-duty electrical protection device engineered for high-capacity power distribution systems. Positioned as the main incoming breaker or major sub-board switch inside industrial and commercial distribution panels, it shields electrical networks from severe damage caused by high-magnitude short circuits and prolonged electrical overloads.
Key Features:
-
High Breaking Capacity: Engineered to safely interrupt massive fault currents, preventing catastrophic damage to downstream electrical equipment and main panel infrastructure.
-
Thermal-Magnetic Trip Technology: Combines a thermal element for time-delayed overload protection and a magnetic element for instantaneous short-circuit protection.
-
Robust Industrial Enclosure: Housed in a heavy-duty molded casing designed to withstand harsh environmental conditions, mechanical shocks, and high thermal stresses.
-
Adjustable settings (Select Models): Higher amperage models often allow fine-tuning of trip settings to match the exact load requirements and coordinate protection selectivities.
-
Ergonomic Trip Handle: Features a clear 3-position toggle interface (ON – TRIPPED – OFF) that simplifies manual operations and fault identification during maintenance.
Amperage Selection Guide:
| Amperage (Rating) | Standard Commercial & Industrial Applications |
| 40A / 63A | Small commercial main incoming switchboards, workshop sub-panels, or dedicated power supplies for mid-sized machinery. |
| 80A / 100A | Standard main breaker for commercial shop lots, office floor sub-boards, central HVAC air-cooled chillers, and larger industrial motors. |
| 200A / 250A | High-capacity main incoming breaker for industrial warehouses, large manufacturing plants, server data centers, and multi-story building distribution boards. |
