PV DC disconnect switch - 2-pole LS32 SMA A2 004660062

Disconnect switch for photovoltaic installations – safety and reliability

This two-pole DC disconnect switch LS32 SMA A2 from ETI-POLAM is a key element in photovoltaic systems, providing safe and effective disconnection of direct current circuits. Designed for both professional installers and end-users, it guarantees protection against overcurrent and overvoltage, and also enables safe maintenance work.

Design and application

This disconnect switch is designed for mounting in distribution boards and for direct installation in PV systems. Its solid construction, based on durable material, ensures long-lasting and reliable operation. The mechanism with a knob allows for easy and intuitive operation, and the frame clamps ensure a secure connection of the wires. This is a permanently mounted device, which translates to stable operation.

Key features and benefits

• Safety first: The safety disconnect function protects the installation from the effects of short circuits and overloads.
• Versatility: It can also be used as a main or repair disconnect switch, which increases its versatility.
• Resistance to external conditions: The IP20 degree of protection provides protection against touching and limited protection against solid objects.
• Optimized for PV: Designed specifically for operation with photovoltaic systems with a voltage of up to 1000V DC and a rated current of 32A.
• Compliance with standards: The product has quality certificates confirming its compliance with applicable safety standards.
• Easy installation: Intended for mounting in distribution boards, it facilitates integration with existing electrical infrastructure.

Technical parameters in practice

The LS32 SMA A2 disconnect switch stands out from the competition primarily due to its purpose – it is an element dedicated to photovoltaic installations. The rated continuous current of 32A makes it suitable for protecting most standard PV circuits. The rated voltage of 1000V DC guarantees compatibility with modern solar systems. The design of the device allows for easy and safe disconnection of circuits during servicing or failure, which is particularly important for installers.
