Safe & reliable installationsTotal reliability and guaranteed safety, combined with low maintenance costs are vital when selecting components for integration into your DC distribution.

Photovoltaic and DC installations must be able to perform in all conditions, even extreme operating environments. INOSYS Load Break Switches have been specifically engineered and tested for the most demanding applications, comply with AS 60947.3:2018 and are UL certified per UL98B.

The INOSYS range also provides integrated shunt trip and undervoltage trip functions as an option. These tripping accessories will not nuisance trip and are immune to voltage fluctuation. The stable ON, OFF and TRIP positions ensure complete disconnection and isolation.

Clear visible contact indicationSafe operation under any circumstances

Reliable switch position• Handle position indicator.

• Fully visible contacts.

• True contact state position indicator.

Perfect arc containment• Fast arc quenching for limiting arc energy (patented dual magnetic

and arc chute chamber technology).

• Specific arc chutes to keep the arc located behind the cover.

Optimum performance

A highly reliable solutionOptimum performance during the complete installation lifecycle

Patented switching technology• Low power dissipation: up to 4 times less than standard switches

thanks to 750 VDC per pole switching capability.

• High perfomance and safety: switch opening and closing are fully independent from the speed of the operator.

High temperature withstand• No derating up to 60 °C

• Wide operating temperature from -25 to +70 °C.

Long lasting stable raw materials INOSYS LBS is an extremely robust product, with all casings made from fiber glass reinforced polyester materials that provide:

• High mechanical withstand

• High stability to temperatures (RTI of 130 °C)

• High dielectric performance (high CTI / tested according to ASTM D 2303).

Guaranteed isolation over time• Designed with materials that maintain

structural integrity.

• Increased creepage distance (doubled compared to AS 60947.3:2018 standard requirements) to ensure no isolation failures.

Ease of installationFlexible configuration, wiring and installation to suit every application

Installation

• Easy integration: the mechanism is centre aligned as standard. For left alignment, please contact NHP.

• Wiring: the complete non polarization of the switch allows all possible types of wiring and connection.

• Mounting: through the pole mounting or external feet that can be oriented.

Connection

• Free access to terminals for flexible wiring.

• Easy access without tools to integrate auxiliary contacts and tripping coil (both located within the switch footprint).

• Simplified fastening with captive nuts, holding the nut while connecting the power bars or cables.
