What Engineers Say

Trusted by Project Engineers Worldwide

"
VoltShield MCCBs were specified into our 11kV/400V substation distribution boards across three process plants. The IEC 60947-2 type test reports were complete, the breaking capacity values verified, and the selectivity tables matched our coordination study precisely. That level of technical documentation is rare among mid-tier manufacturers.
Lars Hendriksen — Senior Electrical Engineer, EPC Contractor, Netherlands   |   Specified: MCCB 400A, 50kA, 3P — 48 units

"We evaluated four RCBO manufacturers for our residential-commercial switchboard line. VoltShield's IΔn accuracy held within ±10% across 5,000 test operations — the tightest variance in our comparative test."

David Okafor — QA Manager, Switchboard Manufacturer, Nigeria

"The electronic trip unit options on the VS-M series MCCB allowed us to configure I²t memory and zone selectivity for our data centre ring main. Commissioning time dropped by 30% compared to our previous supplier."

Priya Nambiar — Systems Integrator, Data Centre Projects, India
