As renewable energy and modern industrial systems demand higher voltages and uncompromising safety, finding a cost-effective and premium-grade main switch is a top priority for engineers and procurement teams. In 2025, Kripal Electric disrupts the market with the launch of the UKP AC and UKGD DC Isolator Switches. These serve as a true high-performance alternative to the ABB OT and OS series.
Engineered for distribution boards, power panels, and high voltage photovoltaic systems, this new series covers capacities from 160A to 800A across 2P, 3P, 4P, 5P, and 6P configurations. By combining a padlockable mechanism, visible break indication, and an advanced laminated dual contact design, the UKP and UKGD series deliver international brand performance at a highly competitive price point.
Key Features Built for Demanding Applications
The UKP and UKGD series are designed specifically for scenarios that require safe isolation and load breaking operations without needing built-in protection such as short circuit or overheating safeguards.
- Exceptional Voltage Capacity: Features a stacked laminated design supporting 1000VDC and 1500VDC, delivering outstanding breaking capacity for solar arrays and energy storage systems.
- Guaranteed Operator Safety: Equipped with a padlockable black knob, a visible window for positive isolation confirmation, and a control transmission shaft.
- Rapid Switching Mechanism: Incorporates an energy storage mechanism for fast make and break operations, independent of the operator speed.
- Versatile Installation: Supports both front and side operation setups.
- Comprehensive Accessories: Compatible with extended handles for external cabinet operation, terminal protection covers, and auxiliary contacts in normally open or normally closed.
Why Kripal Outperforms Legacy Designs
When comparing Kripal to typical domestic manufacturers, the difference lies entirely in the contact architecture and arc quenching technology.

Target Applications for UKP and UKGD Series
Thanks to its robust design, the series is the perfect fit for various demanding sectors.
Solar Photovoltaic Power Plants:
The UKGD DC 1500V is the premier choice for DC main switches, handling high voltages with superior breaking capacity.
Energy Storage Systems:
The stacked high-voltage design ensures stable and reliable isolation for commercial battery racks.
Certifications and Quality Assurance
Compliance with global standards is non negotiable. Kripal is actively finalizing top tier international certifications for the new 2025 range. The TÜV Certification for the UKGD DC series and the SEMKO Certification for the UKP AC series are currently underway. Both ranges fully meet the strict testing requirements of IEC 60947-3 and GB/T 14048.3 standards.
Frequently Asked Questions
Q Can Kripal isolator switches directly replace installed ABB units? Yes. The UKP AC and UKGD DC series are engineered to match the capacity and short time withstand ratings of premium brands. They serve as a seamless and high performance retrofit.
Q Why choose Kripal over cheaper domestic isolator switches?
Cheaper switches use outdated structures that are prone to melting and burning under high loads. Kripal utilizes a premium dual break design with magnetic arc quenching. This translates to a significantly longer lifespan, preventing costly downtime and hazardous electrical fires. The long term return on investment far outweighs the initial price difference.
Q Are these switches suitable for modern 1500V solar installations?
Absolutely. The UKGD DC series is specifically designed for large-scale ground-mounted plants and commercial energy storage systems. Its stacked lamination construction safely handles up to 1500VDC, meeting the strict isolation requirements of modern high voltage renewable systems.
Q What safety features are included?
Standard features include: visible break window for positive isolation confirmation, padlockable handle for lockout-tagout procedures, IP20 terminal protection (with optional covers), and energy storage mechanism for fast, reliable switching regardless of operator speed.
