FICO SLC-30 Mini Size Current Transformer | 30×10mm Window | 30A–300A to 5A Output | SLC Series

The FICO SLC-30 is a compact, molded-housing current transformer (CT) from the SLC Series — designed for reliable current measurement, monitoring and protection in residential, commercial, and light-industrial applications. Engineered to deliver accurate, stable current sensing over a modest primary current range, the SLC-30 is ideal when space is limited and precise metering is required.

 Key Features & Benefits

• Primary current ranges from 30 A up to 300 A — The SLC-30 supports a variety of use cases with primary current ratios like 30/5 A, 50/5 A, 100/5 A, up to 300/5 A, covering many standard electrical load scenarios. This makes it versatile for small to medium electrical systems, distribution panels, HVAC, lighting loads, and machinery protection.
• Compact size & molded housing — The small, robust enclosure makes the transformer easy to install even in compact enclosures or tight panel spaces. Its molded design offers excellent insulation, mechanical strength, and environmental protection. This ensures safe, long-term operation in standard indoor conditions.
• Standard 5 A output secondary current — Delivers a stable, standardized 5 A output to downstream meters, trip units, or monitoring systems — ensuring broad compatibility with common power-metering or protection devices.
• Accurate and reliable measurement — As a measuring-type CT built to meet standard transformer protocols, it ensures the secondary current remains proportional to the primary current under normal operating conditions. This allows precise current measurement and energy monitoring.
• Safe, dry-type conversion with good insulation — The SLC-30 uses air-insulated, dry transformer design with flame-retardant housing, safe for typical low-voltage applications (up to 0.72 kV). Insulation levels and design standards meet CT safety and performance norms.
• Ideal for metering, monitoring and protection systems — Perfect for current measurement, energy metering, load monitoring, and protective relay inputs. Whether for residential panels, small commercial installations, or light-industrial setups, SLC-30 provides reliable performance.
• Easy installation & space-efficient design — Its compact footprint and simple mounting make it suitable for retrofit projects, compact boards, or control cabinets where space is at a premium.

 Typical Applications & Use Cases

• Residential or small-commercial electrical distribution panels.
• HVAC systems, lighting circuits, small motors or other loads up to 300 A.
• Energy meters, power analyzers, load monitoring setups.
• Protection relays, control panels, and overload detection systems.
• Retrofit upgrades or new installations where space is limited or conductor size is moderate.
