VoltShield Industries: Critical Protection Applications

From industrial process plants to hyperscale data centres — IEC and UL certified circuit breakers for every critical sector.

Sector

Industrial Manufacturing & Process Plants

Motor control centres (MCC), distribution boards, and machine panel protection require circuit breakers with defined selectivity, mechanical endurance ratings, and reliable overload protection across continuous duty cycles.

VoltShield VS-M MCCBs are specified in manufacturing facilities requiring 50kA breaking capacity on 400V TN-S systems. The ETU-E configuration with adjustable I-S-L protection curves enables precise motor starting coordination without nuisance tripping during high-inrush periods.

Key parameters: Icu up to 50kA, Ics = 100% Icu, thermal memory (I²t), IP65 available for harsh environment panels.

Sector

Data Centres & Critical Infrastructure

Data centre power distribution demands total selectivity between all circuit protection levels — a single unplanned trip at the wrong level can cascade into service outages across thousands of servers.

The VS-M ETU-C with Zone Selective Interlocking (ZSI) ensures that under short-circuit conditions, only the breaker directly upstream of the fault operates — fault clearing in under 50ms while all other feeders remain live. Modbus TCP integration provides real-time current and energy data for DCIM systems.

Sector

Commercial Buildings & Real Estate

Commercial tenant distribution boards and common-area circuits require residual current protection (RCCB/RCBO) to meet IEC 60364 and local building electrical regulations. Personnel protection at 30mA IΔn is standard; equipment protection at 300mA IΔn is specified for sensitive IT loads.

VoltShield VS-R RCBO combines type-A residual current sensing (detects pulsating DC residual currents from SMPS loads) with adjustable overcurrent protection — a single-module solution for modern building services.

Sector

Energy & Utilities / Renewable Generation

Substation secondary distribution, PV inverter output protection, and wind farm auxiliary power boards all demand circuit breakers rated for bidirectional fault current, high fault levels, and operation over wide temperature ranges.

VS-M MCCB rated at 690V AC with Icu = 36kA is specified in 0.4/0.69kV transformer LV boards. The IK10-rated enclosure option supports outdoor substation installations in exposed environments from -25°C to +70°C.

Sector

Oil, Gas & Petrochemical

Hazardous area Zone 1 and Zone 2 installations require ATEX and IECEx certified equipment for Group IIC gases. Our hazardous area MCCB enclosure options (available through certified integrators) meet Ex d IIC T4 Gb classifications.

Standard VS-M MCCBs are specified in non-hazardous area auxiliary panel rooms, control buildings, and instrument power distribution throughout refineries and offshore platforms, where Icu = 50kA, IP54 minimum and tropical rating are required.
