Siemens miniature circuit breaker 5SY series specifications and application wiring

Brief introduction of Siemens miniature circuit breaker 5SY series

The miniature circuit breakers in this series of Siemens can be divided into two types: AC and DC. At the same time, the minimum current level coverage is 0.3A and the maximum is 80A, and the number of poles is from 1 to 4. The trip curve characteristics of Siemens miniature circuit breakers are B, C, D three types, and the maximum breaking capacity can reach 50kA.

Generally speaking, Siemens 5SY series includes 5SY6-6000A (standard type), 5SY4-10000A (high breaking type), 5SY7-15000A (ultra-high breaking type), 5SY5-10000A (DC type), 5SY7...MA Single-magnetic miniature circuit breakers, 5SY60-6000A (compact type) and other miniature circuit breakers of different specifications.

◆With 4 core upgrades:

1. Window design: It can accurately indicate, and you can directly observe and understand the working state of the circuit breaker contacts. The green indicator means disconnection, and the red indicator means power on.

2. Anti-finger contact design: The terminal block has anti-finger contact protection. In order to ensure the safety during installation or wiring, Siemens miniature circuit breakers adopt an insulated, dust-proof and anti-touch design, which can improve the service life of the equipment at the same time. It also minimizes the risk of electric shock.

3. Sliding buckle design: No tools are required when installing or disassembling the circuit breaker, which can be faster and has a significant improvement in efficiency.

4. Handle design: The ergonomic shape is adopted, and the non-slip pattern handle fully considers and fits the characteristics of ergonomics, so that the operation can be more labor-saving and more comfortable.

5SY is suitable for a full range of miniature circuit breakers for all applications. The rated current is 0.3A to 80A, 6/10/15kA short circuit breaking capacity, and has three characteristic curves of B/C/D. The implementation standards are IEC60898-1/-2, IEC60947-2, GB10963.1/.2, and GB14048.2. The application areas of miniature circuit breakers are non-residential buildings, residential buildings, and industries.

The 5SY compact type is suitable for socket circuits and lighting circuits that require an open and closed neutral line in all building installations, and can save space in the distribution box. The executive standards are IEC60898-1, GB10963.1, and the application areas of miniature circuit breakers are non-residential buildings, residential buildings, and industries.

Features of Siemens miniature circuit breaker 5SY series

MCB miniature circuit breakers are widely used in construction and industry to protect system circuits and equipment. At the same time, it is mainly used for the main control switch of equipment disconnection and isolation. In industrial occasions and engineering projects, Siemens circuit breakers will also install additional accessories, such as auxiliary contacts, fault alarm contacts, shunts, and undervoltage trips. Remote control devices and leakage accessories to achieve remote communication and control functions.

◆The upper and lower wire entry method of the miniature circuit breaker depends entirely on the actual installation needs (but the DC miniature circuit breaker is selected according to the fixed polarity). The dual-terminal design allows two wires to be connected at the same time during installation and use, and the wiring space is changed. Larger, terminal wiring is easier.

◆The circuit breaker body can be removed faster and easier from the busbar, and the fast busbar operation saves the replacement time to a great extent. If the busbar installed afterwards can make the wire connection more clearly visible .

◆The installation of Siemens miniature circuit breaker 5SY series accessories is relatively convenient and simple, and can be completed without any external tools. For the 1PN equipment of 5SY60 model specification, the incoming line can be entered from the upper part or the lower part, and the side auxiliary terminal can also be used to realize additional wiring when a larger wiring capacity is required.
