Metal Clad & Withdrawable Switchgear – High-Safety, High-Availability Power Distribution

In mission-critical facilities, even a second of electrical downtime can have catastrophic consequences. BECO, Symbol of Distinction, delivers Metal Clad & Withdrawable switchgear systems engineered for maximum operational safety, uptime, and modular flexibility.

Designed to IEC 62271-200 standards, these arc-resistant assemblies can withstand 40 kA fault currents for 1 second, protecting both operating personnel and connected equipment. The four-compartment segregation ensures that busbars, circuit breakers, cable terminations, and low-voltage controls are housed in individually isolated sections, allowing safe access during live operation.

The withdrawable architecture supports motorized racking of circuit breakers, enabling operators to insert or remove breakers with precision and minimal effort—perfect for facilities that demand continuous power availability. Each compartment features grounded metal barriers to minimize arc-flash propagation.

Industries such as oil refineries, data centers, and hospitals rely on this technology for uncompromised reliability. When combined with IEC 61850 digital protection relays, operators gain enhanced protection, remote monitoring, and system diagnostics—prolonging system life and improving predictive maintenance efficiency.

Arc-Resistant Design – 40 kA Tested Safety

Electrical arcs are among the most dangerous events in medium voltage switchgear operation. BECO’s Metal Clad & Withdrawable systems are tested and certified for arc resistance at 40 kA for 1 second, in compliance with IEC 62271-200 performance categories.

Arc-resistant features include:

• Fully grounded metal partitions between compartments.
• Pressure relief ducts to safely vent hot gases away from operators.
• Robust mechanical interlocks preventing unsafe breaker operation.
• Arc detection & rapid switching through integrated digital relays.

This level of fault handling ensures operational continuity during faults while containing and redirecting arc energy to keep maintenance personnel safe. This is particularly critical for oil and gas facilities and hospital power systems, where unplanned outages can cause both financial and life-safety consequences.

Withdrawable Technology – Motorized Racking for Zero Downtime

The withdrawable circuit breaker design is the backbone of uninterrupted maintenance. BECO panels allow breakers to be inserted (“racked-in”) or isolated (“racked-out”) without shutting down the entire switchboard—a vital feature for high-availability sites.

Motorized racking systems deliver added precision, reducing manual handling errors and allowing remote operation when required. The ability to quickly replace a circuit breaker without extended outages significantly lowers maintenance costs and boosts operational uptime.

Given that the architecture follows Form 4 compartmentalization, each breaker can be serviced or replaced while adjacent circuits continue operating—ideal for data centers, industrial processing plants, and healthcare facilities where downtime is unacceptable.

Digital Protection & IEC 61850 Integration

Every BECO Metal Clad & Withdrawable switchgear system can be fitted with digital protection relays that comply with IEC 61850 standards. This allows seamless integration into modern SCADA and energy management systems for real-time monitoring, remote fault diagnosis, and automated fault isolation.

Digital relays enable:

• Precise fault detection and trip control.
• Event recording for incident analysis.
• Predictive maintenance alerts to anticipate component failure.
• Remote control and system health monitoring.

This capability transforms traditional switchgear into a smart, connected power distribution asset, providing not only switching and protection but also condition-based asset management.

Modular Design – Reduced Footprint, Increased Flexibility

BECO’s modular approach allows facilities to scale capacity without major redesigns. Each functional unit of the Metal Clad & Withdrawable system is pre-engineered and factory-tested, minimizing installation time while ensuring compliance with all safety and operational specifications.

The modular layout helps reduce overall switchgear footprint, a key factor in space-constrained environments such as data centers and urban substations. Pre-configured modules also simplify upgrades and expansions—allowing operators to add capacity without prolonged outages.

Compared to conventional fixed systems, this modular design offers 15% higher fault tolerance, lower lifecycle costs, and operational resilience that is unmatched in its category.

Industry Applications – Oil Refineries, Data Centers, Hospitals

Oil Refineries – With high fault potential and explosive atmospheres, arc-resistant switchgear is vital for safety compliance and operational continuity.
Data Centers – Downtime can lead to massive data and financial losses; withdrawable modules ensure zero power interruption during maintenance.
Hospitals – Life-critical systems demand unbroken electrical supply; motorized racking allows safe servicing without halting essential services.

In each of these sectors, BECO , Symbol of Distinction, ensures premium engineering, unmatched safety, and maximum uptime.
