Schneider MCB 4P 16A

Description

Product Description This is an industrial-grade electrical safety device designed to protect electrical circuits from damage caused by excess current from an overload or a short circuit. As a 4-Pole (4P) breaker, it is engineered to simultaneously control and protect three distinct phase wires (live lines) plus the neutral line in a three-phase electrical system. Key Features 4-Pole Protection: Safely interrupts all three phases and the neutral line at the exact same moment if a fault is detected. 16A Current Rating: Tailored to protect circuits running equipment or sub-panels up to a maximum continuous load of 16 Amps. Trip Characteristics (Typically C-Curve): Most variants of this specific model feature a “C” tripping curve, meaning it trips instantly when it detects a current 5 to 10 times its rated load. This makes it perfect for commercial or light industrial loads with moderate inductive inrush currents. DIN Rail Mounting: Features a standard clip-on back mechanism designed to snap effortlessly onto standard 35mm DIN rails inside electrical distribution boards. VisiSafe & VisiTrip Indicators: Many Schneider Acti9 models feature a distinct green strip to guarantee physical disconnection safety during maintenance, alongside a red flag indicator to show exactly which breaker tripped due to a fault. Compatible Mechanisms and Systems As a core power distribution component, this MCB does not operate as a standalone consumer device; instead, it is designed to be integrated with specific electrical mechanisms and infrastructure: 1. Compatible Enclosures and Distribution Hardware Electrical Distribution Boards (DBs): Snaps directly into three-phase electrical panel boards, consumer units, and industrial control panels equipped with standard DIN rails. Busbar Systems: Compatible with Schneider’s tooth or pin-type comb busbars for clean, efficient multi-breaker power bridging inside the panel. Auxiliary Add-ons: Can be mechanically coupled side-by-side with official Schneider Acti9 accessories, such as auxiliary contacts (iOF), fault indicating contacts (iSD), or shunt trips (iMX) for remote monitoring and automation. 2. Machinery and Loads It Protects A 4P 16A circuit breaker is commonly matched to protect the following three-phase electrical mechanisms: Small Industrial Motors & Pumps: Three-phase water pumps, exhaust ventilation fans, and conveyor belt motors that require a balanced phase supply and draw less than 16A. HVAC Systems: Commercial air conditioning compressors, multi-split cooling systems, and large electric heating blocks. Workshop Machinery: Small commercial workshop tools such as air compressors, light-duty CNC machines, and industrial packaging machinery. Three-Phase Sub-Panels: Serves perfectly as a localized main isolator or feeder breaker for a smaller downstream breaker box or server rack power distribution unit (PDU).
