Accessories for Industrial Automation and Electrical Distribution
In the world of industrial automation and electrical distribution, accessories are the unsung heroes that ensure systems operate reliably, safely, and efficiently. These components, ranging from auxiliary contacts and shunt trips to mechanical interlocks and terminal shrouds, are designed to complement and enhance the functionality of main devices like circuit breakers, contactors, and motor starters. When selecting accessories, key technical parameters include rated operational voltage (e.g., 230V AC, 400V AC), rated insulation voltage (Ui), rated impulse withstand voltage (Uimp), and thermal current (Ith). For auxiliary contacts, the number of normally open (NO) and normally closed (NC) poles is critical, while for shunt trips, the operating voltage range and power consumption matter. Mechanical interlocks ensure safe sequential operation, and terminal shrouds provide IP2X protection against accidental contact. These accessories are engineered for specific mounting types, such as DIN rail, screw fixing, or plug-in, and are often rated for a mechanical endurance of up to 10 million operations.
Accessories are deployed across a wide spectrum of sectors and environments. In industrial manufacturing plants, they are integral to motor control centers (MCCs) and programmable logic controller (PLC) panels, where they enable remote tripping, status indication, and interlocking of safety circuits. In commercial buildings, they are used in main distribution boards (MDBs) and sub-distribution boards (SDBs) for lighting, HVAC, and power systems. In renewable energy installations, such as solar photovoltaic (PV) arrays and wind turbines, accessories ensure proper coordination between inverters, switchgear, and protection devices. They are also critical in data centers, where they support redundant power distribution and automatic transfer switches (ATS). The harsh environments of oil and gas, mining, and water treatment plants demand accessories with high ingress protection (IP) ratings, such as IP65 or IP67, and resistance to vibration, temperature extremes, and corrosive atmospheres.
Our comprehensive catalog of accessories includes several key subcategories and article codes. For auxiliary contact blocks, we offer the ABB OA1G10 (1 NO + 1 NC) and OA2G20 (2 NO + 2 NC) series, as well as the Schneider Electric LADN22 (2 NO + 2 NC) and LADN11 (1 NO + 1 NC) for TeSys contactors. For shunt trips, the Siemens 5ST3010-0CC (230V AC) and 5ST3010-0CD (400V AC) are popular choices. Mechanical interlocks include the ABB MVS-1 for SACE circuit breakers and the Eaton NZM2-XR208 for NZM series. Terminal shrouds and covers are available for the ABB SACE Tmax and Emax ranges, such as the T5-6X and E1-2X. The article codes typically follow a pattern: a prefix indicating the brand or series (e.g., OA for ABB, LAD for Schneider, 5ST for Siemens), followed by a numeric code for the specific function and electrical rating. For example, the code "LADN22" breaks down as "LAD" for the TeSys D series auxiliary contact block, "N" for the standard version, and "22" for 2 NO + 2 NC contacts.
