Frequently Asked Questions for Q140
The Siemens Q140 miniature circuit breaker (MCB) is designed to provide overload and short-circuit protection for final circuits. It offers quick interruption of fault currents, thermal-magnetic trip characteristics, compact DIN-rail mounting and clear ON/OFF indication. This makes the Q140 suitable for use in DBs, sub-distribution boards and control panels.
The Siemens Q140 MCB is suitable for lighting circuits, socket-outlet circuits, small motor loads and general-purpose AC circuits. Depending on its tripping curve (such as B, C or D), it can be optimized for resistive, inductive or high inrush loads. It is typically used in residential, commercial and light industrial installations.
To select the correct Siemens Q140 MCB, match the rated current to the circuit load and cable capacity, and choose an appropriate trip curve based on the inrush characteristics of the connected equipment. For standard lighting and socket circuits, curve B or C is commonly used, while motor or transformer circuits may require curve D. Always follow local wiring regulations when selecting the MCB rating.
The breaking capacity of the Siemens Q140 MCB defines the maximum short-circuit current it can safely interrupt without damage. Choosing an MCB with adequate breaking capacity according to the prospective fault level at the installation point is essential for safety. The exact Icu/Icn rating is provided in the product datasheet and should be checked before selection.
The Siemens Q140 MCB is typically mounted on a DIN rail inside the distribution board. Ensure that the line and load terminals are correctly connected, torque settings are respected and suitable busbars or cables are used. All installation work should be carried out by a qualified electrician following local electrical standards.
The price of Siemens Q140 MCB depends on its pole configuration, rated current and breaking capacity. For current pricing, offers and stock availability, visit Electrihub and search for Q140. You can compare variants and select the one that best matches your application.
The datasheet for Siemens Q140 MCB includes detailed information on trip curves, breaking capacity, derating factors and wiring instructions. You can download the latest datasheet from the Q140 product page on Electrihub or from the official Siemens documentation to ensure compliant design and installation.
The Siemens Q140 miniature circuit breaker is designed for reliable overload and short circuit protection. It offers precise tripping characteristics, high breaking capacity, long mechanical and electrical life, and compatibility with Siemens distribution boards and enclosures.
It is widely used in residential, commercial, and industrial distribution boards, control panels, feeder circuits, and final sub circuits requiring dependable protection.
It automatically disconnects the circuit when overload or fault currents exceed the set limits, helping prevent cable overheating, equipment damage, and potential fire hazards.
Check the rated current, number of poles, breaking capacity (kA), tripping curve (B/C/D), system voltage, and coordination with upstream and downstream protective devices.
Ensure correct DIN rail mounting, proper line and load connection, torque tightening of terminals, and adherence to Siemens wiring diagrams and local electrical standards.
Pricing varies based on rating, poles, and series. Visit Electrihub to view current Siemens MCB prices, offers, and stock availability.
