Suppressors, also known as surge arresters, transient voltage surge suppressors (TVSS), or lightning arresters, are critical components in electrical and industrial automation systems. These devices protect sensitive equipment from voltage spikes, transients, and surges caused by lightning strikes, switching operations, or grid disturbances. In the context of low-voltage distribution and control panels, suppressors are typically rated for specific voltage levels (e.g., 230V, 400V AC) and surge current capacities (e.g., 20kA, 40kA, 100kA per mode). They come in various configurations, including single-pole (1P), two-pole (2P), three-pole (3P), and four-pole (4P) versions, often with integrated thermal disconnection or remote signaling contacts for monitoring. Key technical parameters include nominal discharge current (In), maximum discharge current (Imax), voltage protection level (Up), and response time (typically <25 ns). Suppressors are available as Type 1 (for direct lightning strikes), Type 2 (for switching surges), and Type 3 (for sensitive end-device protection), each with distinct installation requirements and performance characteristics.
Suppressors are widely deployed in industrial automation environments, including motor control centers (MCCs), programmable logic controller (PLC) cabinets, variable frequency drive (VFD) panels, and building management systems. They are also essential in commercial and residential electrical installations, such as main distribution boards (MDBs), sub-distribution boards (SDBs), and uninterruptible power supply (UPS) systems. In sectors like manufacturing, oil and gas, renewable energy (solar and wind farms), data centers, and telecommunications, suppressors ensure operational continuity by preventing damage to costly automation hardware, sensors, and communication networks. Their installation is often mandated by standards like IEC 61643-11 or UL 1449, depending on regional regulations.
Within our catalog, the MR02 category includes a range of surge protective devices (SPDs) and suppressors. Key subcategories include Type 1+2 combiners, Type 2 modular suppressors, and Type 3 socket-mounted protectors. For example, the article code structure for our main suppressors follows a pattern like MR02-XXX-YYY, where XXX indicates the voltage rating (e.g., 230 for 230V, 400 for 400V) and YYY denotes the surge current capacity (e.g., 020 for 20kA, 040 for 40kA). Specific codes include MR02-400-040 (400V, 40kA Type 2) and MR02-230-020 (230V, 20kA Type 3). These products are designed for DIN-rail mounting, with optional plug-in modules for easy replacement without rewiring.
At Electric Automation Network, we offer a comprehensive selection of suppressors with real-time pricing and detailed technical documentation for each article.
