Find fuses, circuit breakers, polyfuses and surge protection in Samrand. Local stock, branch pickup, quotes and spec guidance for makers, students and procurement.
Fast collection from Samrand with VAT invoicing and account quotes available.
Fuses, breakers, polyfuses and surge protection across board and panel options.
Compare datasheets, calculate fuse sizing and check trip curves before buying.
If you need fuses, circuit breakers, surge protection, resettable polyfuses or panel-mounted protection for projects and installations, Communica's Samrand warehouse stocks a broad range suitable for hobby, education and light industrial use. This landing page outlines the types of devices, where they fit, and how to check local stock and specifications before you buy.
Match devices to your circuit by confirming rated voltage, rated current, breaking capacity, time-current characteristic (fast/slow), and package or mounting style. For board-level protection look at hold current (Ih) and trip current (It) on polyfuses; for mains breakers check pole configuration and trip curve (B, C, D types) if available on the datasheet.
Tip: For prototype work, keep a small assortment of 1A, 2A, 5A and 10A fuses and a few 1-6A polyfuses. Visit the Samrand branch to confirm physical fit and datasheet details.
| Device | Typical use | Key spec to check |
|---|---|---|
| Cartridge fuse | Mains and high-current DC lines | Voltage rating, I²t, breaking capacity |
| Mini circuit breaker (MCB) | Distribution panels, machinery | Amp rating, trip curve, poles |
| Resettable polyfuse (PTC) | USB ports, power supplies, boards | Hold current (Ih), trip current (It), max voltage |
Consider holders, DIN-rail mounts, fuse clips, and busbar accessories when planning installations. Communica stocks many of these accessories across its product categories; browse relevant categories to compare mounting options and brands for enclosures and connectors at Collections and view brand options at Shop by Brand.
Stock levels and lead times vary by part and brand. Use the Samrand branch for fastest collection. Check branch hours and pickup options at Branches & Trading Hours before visiting. For account customers and procurement teams, request a quote or a VAT invoice when placing an order for bulk or educational purchases.
Select protection based on the normal operating current plus a margin. Use Ohm's law and power formulas for preliminary sizing:
V = I × R (Ohm's law). P = V × I (electrical power). For example, a 12 V LED strip drawing 3 A requires a fuse rated slightly above 3 A - typically 1.25× to 1.5× the operating current depending on inrush and thermal environment.
If a motor runs at 24 V and draws 4 A steady with 10 A stall current, choose a protection strategy: a slow-blow fuse rated to tolerate short inrush (for example 6-8 A slow-blow) or a breaker with a suitable magnetic trip to handle stall conditions. Document estimated inrush and reference datasheets before selecting the exact part.
Communica offers component bundles for education and prototyping that often combine fuses, holders and basic DIN-rail breakers. When buying, check product pages for included accessories and compatibility notes; browse all products to compare part numbers at buy circuit protection devices or start from the homepage for general navigation at Communica Homepage.
For procurement teams, Communica can provide formal quotes and VAT invoices for purchase orders. Request compatibility guidance and quote details when placing larger orders or educational lab kits - the Samrand warehouse is the central dispatch point for national deliveries and branch collection. See company background and experience for trust context at best suppliers of electronic components in Samrand.
Example: a small lab needs ten 2 A slow-blow cartridge fuses for student kits. Expect single-unit prices to vary by brand and type; budget estimates in ZAR depend on supplier bracketing and whether holders are included. For precise pricing and availability, check the Samrand stock listing or request a quote to receive VAT invoicing and lead-time estimates.
