Eaton P-SOL4/32/4 photovoltaic dc load switch

The Eaton P-SOL4/32/4 load switch is an apparatus designed for the safe connection of DC circuits in photovoltaic installations, providing effective disconnection of PV strings at load. The design of the device meets the requirements of standards for high-voltage DC circuits and enables reliable operation in PV switchgear.

Dedicated to DC photovoltaic installations with a rated current of 32 A and 4 poles.
Adapted for operation in high voltage DC circuits suitable for PV stringing.
Capable of modular installation in standard switchgear.
Ensuring safe disconnection under load due to the load breaker design.
Solution in accordance with safety requirements for DC circuits.

Application in photovoltaic installations

The Eaton P-SOL4/32/4 load switch is designed for connecting and disconnecting DC circuits in photovoltaic systems, in particular for disconnecting individual PV strings from the rest of the installation. The apparatus allows safe service and maintenance work by quickly disconnecting the DC power supply on the panel side. The solution is suitable for rooftop and ground-mounted applications, both in domestic and commercial installations, where reliable disconnection of DC circuits is required. The device meets the requirements for safety and quality of operation in the PV environment, ensuring durability and stability of parameters throughout the expLoatation period

Design and functions of the device

The P-SOL4/32/4 is a DC load disconnector with a modular design for easy installation in standard DIN-rail switchboards. Four poles allow flexible configuration of connections in typical photovoltaic systems, and appropriately selected current-voltage parameters ensure correct operation in PV string circuits. The apparatus allows manual disconnection and switching, and the switching mechanism is optimized for DC operation, which increases the safety and durability of the contacts. The insulation materials used and the design of the housing allow use in typical environmental conditions for PV switchgear

Safety expLoatation

The Eaton P-SOL4/32/4 DC load switch is designed for safe expLoatation in high-voltage DC circuits. The device reduces the risk of arcing when disconnecting loaded DC circuits, which is critical in photovoltaic systems. Thanks to the clear on and off position, it is possible to clearly assess the operating status of the apparatus, which contributes to operator safety. The switch supports compliance with service procedures and regulations for electric shock and fire protection in PV installations

FAQ (customer)

Q: Is this switch suitable for my home rooftop PV installation?
A: Yes, it is designed for DC circuits in photovoltaic systems and can be used in typical residential rooftop installations, provided the current and voltage of the strings match the switch ratings.
Q: Can I use it to compLetely turn off my solar panels for maintenance?
A: It is intended to disconnect DC strings from the rest of the system, allowing safer maintenance on downstream equipment; panels themselves will still generate voltage in sunlight.
Q: Does it fit into a standard DIN-rail distribution board?
A: Yes, the device is modular and suitable for mounting on a standard DIN rail in PV distribution boards.
Q: Do I need an electrician to install this product?
A: Installation and connection should be carried out by a qualified electrician familiar with DC PV systems and local regulations.
Q: Is this switch only for solar appLications?
A: It is optimized and specified for photovoltaic DC appLications and should be used primarily in such systems.
Q: Does it have visible ON/OFF indication?
A: Yes, the handle position provides clear indication of the ON and OFF states.

FAQ (expert)

Q: Can this device be used for bi-directional DC currents in PV systems with batteries?
A: It is specified as a DC load break switch for PV strings; for battery circuits or bi-directional operation, check detailed technical documentation and coordination with system design requirements.
Q: Is there any specific wiring recommendation for polarity on the poles?
A: Follow the wiring diagrams and manufacturer’s instructions for proper pole allocation and polarity to ensure correct arc quenching and isolation.
Q: How should it be coordinated with DC fuses or string breakers?
A: It is typically used in combination with string fuses or DC circuit breakers; select protective devices based on system current, voltage, and selectivity requirements.
Q: Is the device suitable for use in systems with high short-circuit current from multipLe strings?
A: Check the rated short-circuit withstand and coordination data in the technical documentation before using in systems with high fault currents.
Q: Can it be used in outdoor enclosures?
A: The switch itself is designed for installation inside an enclosure; for outdoor use, pLace it in a suitably rated weatherproof distribution box.
Q: Are accessories such as auxiliary contacts available?
A: For information on auxiliary contacts or other accessories, refer to the product family documentation and Eaton catalog.
