Main Isolator Switch

An isolator switch, also known as a main disconnect switch, is a manually operated electrical device. Its primary purpose is to safely isolate a circuit from the main power supply during maintenance or repair, creating a visible, physical break in the circuit. It provides a safe working environment for electricians and maintenance engineers and is a crucial safety device for preventing electric shock.

The number of poles you need depends on your electrical supply system:

• 1-Pole & 2-Pole: Used for single-phase systems. A 1-Pole switch disconnects only the live wire, while a 2-Pole switch isolates both live and neutral wires, offering a higher level of safety. They are commonly used in residential distribution boxes and small commercial panels.
• 3-Pole & 4-Pole: Used for three-phase systems. A 3-Pole switch disconnects the three-phase conductors, and a 4-Pole switch disconnects the three phases plus the neutral. They are essential for equipment like industrial motors and three-phase air conditioning units.

The KRIPAL series offers a complete range of pole configurations to cover your needs, from residential to small and medium-scale industrial applications.

The KRIPAL series of modular isolating switches is built to handle a robust rated current of up to 100 Amps, enabling it to cover a wide range of mainstream power distribution requirements.

Safety is our top priority. KRIPAL Isolating Switch Disconnectors are manufactured in strict compliance with the international IEC 60947-3 standard, ensuring they meet rigorous requirements for performance, safety, and durability.

KRIPAL switches feature a compact design that saves valuable space inside distribution boards and panels. This makes them the ideal solution for applications with high layout density, allowing for more efficient and organized electrical installations, particularly in residential distribution boxes and small commercial panels.

Yes. The KRIPAL series is designed for versatility. The availability of different pole configurations (1P to 4P) and the high 100A current rating enable it to cover mainstream power distribution needs—from residential and retail spaces to small and medium-scale industrial applications, such as controlling industrial motors or three-phase HVAC systems.

A reliable and trusted main disconnect switch is the primary safety defense for electricians and engineers. It is designed to safely and completely isolate circuits from the main power supply, ensuring that maintenance and repair work can be performed with zero risk of electrocution. It is a non-negotiable component of any safe electrical system.
