Anchor Roma 25A Modular MCB

Product Details

Key Specifications & Features Current rating: 25 A (single‑pole for example model “66155B”). Tripping characteristic / curve type: “C”‑curve version (meaning it allows moderate inrush current before tripping, suited for general loads). Poles: Available in Single‑Pole (SP) and Double‑Pole (DP) variants. For example SP model “66155B” and DP model “66161B”. Breaking capacity: 3 kA (3000 A) short‑circuit breaking capacity noted in listings. Rated voltage: ~240 V AC (single phase) for typical variant. Material / build: Housing made of polycarbonate / moulded flame‑retardant plastic. For example one listing states “Material: Polycarbonate”. Series / finish: Part of the Roma Urban / Roma Plus / Classic modular line — meaning modular mounting, aesthetic finishes, colour variants. Example: model “66155S” (silver finish). --- Applications & Considerations The 25 A rating makes this MCB appropriate for circuits drawing moderate current loads — heavier than the standard lighting/fan circuits (10–16 A) but not massive motor loads (which might need higher rated breakers or dedicated motor starters). In a modular distribution board setup (in a home, office or hospitality installation), the mini modular format of the Roma series allows sleek mounting and integration with other modular devices (switches, sockets, etc). If you install this in a coastal/humid area (like Chennai, Tamil Nadu), ensure proper wiring, good quality termination, and that the panel/enclosure protects against moisture and dust — the build quality is good, but environment still matters. Ensure upstream wiring, cable size, protective devices, and load calculations are aligned with the 25 A rating (i.e., don’t just install a 25 A breaker if your wires are sized for 10 A). Check model variant: some variants may have finish differences (white/black/silver) or number of poles; the datasheet and packaging should match your need. --- What To Verify Before Purchase or Installation Exact Part Number: e.g., SP variant “66155B”, DP variant “66161B” (or Roma Plus variant “89990”). Confirm you’re getting the correct one for your installation. Tripping Curve: Confirm “C” curve is appropriate (for general use). If your circuit has high inrush (motors, compressors) maybe an “D” or motor‑rated breaker is needed. Breaking Capacity: Make sure the 3 kA (or whatever spec) matches the available fault current for your installation. Mounting / Module Width: Since this is a mini modular unit, check your distribution board has space and proper rail/slots for modular MCB mounting. Finish and Aesthetics: If you’re matching with other modular devices from the Roma range (switches, sockets), pick colour/finish accordingly (white, black, silver). Material / Standards: Ensure the housing is flame‑retardant plastic (with appropriate rating), the product carries IS/IEC compliance (e.g., IS/IEC 60898‑1) and brand authenticity. Environment & Wiring: Ensure quality installation — good cable gauge, correct torque on terminals, proper earthing, good ventilation/protection from moisture.
