Low- & Medium-Voltage Switchgear Solutions for North American Projects
RICHES POWERTECH® provides UL 1558 low-voltage switchgear and project-specific medium-voltage switchgear solutions for North American industrial, commercial, utility, renewable energy, data center and infrastructure projects.
Power Distribution Challenges
Complex Power Distribution Requirements
Large-scale industrial, commercial and utility projects require multi-layered power distribution with coordinated protection, metering and redundancy across multiple voltage classes.
Short-Circuit Coordination
High available fault currents demand switchgear with adequate short-circuit ratings, protective relay coordination and arc flash mitigation strategies.
Multi-Voltage Integration
Projects often require both low-voltage (600V class) and medium-voltage (1kV–38kV) switchgear that must integrate seamlessly within a single power distribution system.
Reliability and Redundancy
Mission-critical facilities require main-tie-main configurations, redundant feed sources and rapid maintenance capabilities to minimize downtime.
Low-Voltage Switchgear Solutions
Our UL 1558 low-voltage metal-enclosed switchgear is designed for 600V-class power distribution applications with drawout or fixed air circuit breakers, compartmentalized construction and project-specific ratings.
UL 1558 Metal-Enclosed Switchgear
Low-voltage metal-enclosed switchgear with drawout or fixed air circuit breakers (ACB), compartmentalized construction and project-specific ratings for voltage, ampacity and short-circuit capability.
Main-Tie-Main Configurations
Dual-bus switchgear arrangements with tie circuit breakers for redundant power distribution, enabling maintenance on one bus without interrupting service to critical loads.
Drawout Circuit Breakers
ACB drawout configurations for rapid breaker replacement without disconnecting primary conductors, reducing maintenance time and improving system availability.
Integrated Protection and Metering
Current transformers (CT), potential transformers (PT), protective relays and power metering integrated into each switchgear section for comprehensive monitoring and control.
Medium-Voltage Switchgear for 1kV–38kV Applications
RICHES POWERTECH® provides project-specific medium-voltage switchgear solutions for applications from 1kV to 38kV, subject to the applicable technical and certification requirements. Medium-voltage switchgear configurations include metal-enclosed and metal-clad assemblies with vacuum circuit breakers.
Metal-Enclosed Switchgear
Grounded metal enclosures with compartmentalized construction for enhanced safety and structural integrity in medium-voltage applications from 1kV to 38kV.
Metal-Clad Switchgear
Removable shuttered assemblies with separate compartments for instruments, relays, bus and vacuum circuit breakers per applicable ANSI/IEEE standards.
Vacuum Circuit Breakers (VCB)
Medium-voltage vacuum interrupters in drawout or fixed-mounted configuration for switching and protection, providing long mechanical and electrical life.
Protection and Control Systems
Microprocessor-based protective relays for overcurrent, ground fault, differential, distance and other protection functions with SCADA communication interfaces.
Note: Medium-voltage switchgear is engineered according to the applicable project standards (ANSI, IEEE, NEMA, CSA, IEC or other). The applicable standard and certification pathway depend on the voltage class, product construction and project specification.
