Understanding the BlokSet Low Voltage Switchboard System
What Is a BlokSet Low Voltage Switchboard?
A BlokSet low-voltage switchboard is a factory built, Metal-Enclosed power distribution system for managing electrical loads-usually in applications up to 600 volts in commercial and industrial facilities. Modular construction means distributors can create their individual layouts to suit customer requirements, incorporating circuit breakers, busbars and protection relays in a smallest possible space – in some cases reducing the floor footprint by 35% while still complying with IEC 61439.
Core Functions and Industrial Applications
BlokSet switchboards serve three primary roles: power distribution, fault protection, and load monitoring. They route electricity from transformers to downstream equipment while isolating faults through arc-resistant enclosures and magnetic-actuated breakers. Common applications include:
- Manufacturing plants: Ensuring uninterrupted power for heavy machinery
- Data centers: Balancing critical loads with <600V distribution
- Healthcare facilities: Providing redundant circuits for life-support systems
These systems maintain stable busbar temperatures even at 95% load capacity, making them ideal for environments with fluctuating power demands like renewable energy installations and EV charging hubs.
Key Features and Technical Specifications

Engineered for industrial use, the switchboard handles:
- Continuous currents up to 6,300A
- Operational voltages reaching 690V
- Short-circuit withstand capacity of 100kA/1s (IEC 61439-2 certified)
Safety mechanisms include:
- Fault isolation in 30ms via magnetic actuators
- Arc-resistant containment chambers
- Ground fault monitoring with <10mA sensitivity
- Mechanical interlocks for operator protection
Environmental Durability and IoT Integration
With IP55/IP65-rated enclosures, the system withstands:
- Temperatures from -25°C to +70°C
- 95% relative humidity
- Salt spray exposure (per ASTM B117)
IoT-ready features enable:
- Real-time harmonic analysis (THD <3%)
- Wireless communication (Modbus, Profinet, IEC 61850)
- Predictive maintenance algorithms
Evaluating Configuration Options
Fixed vs. Withdrawable Units
Fixed designs offer 15–20% cost savings for stable operations, while withdrawable units reduce downtime risks by 40% in facilities requiring frequent maintenance.
Single vs. Double Busbar Systems
Double busbar configurations provide:
- 98.6% uptime during partial failures
- 32% less hotspot formation under peak loads
- 25–30% greater capacity expansion potential
This makes them ideal for critical environments like hospitals and chemical plants.
