Sintermetal-EC

What Sintermetal-EC does

Sintermetal-EC is a privately held Serbian industrial manufacturer founded in 1986 in Belgrade, specializing in wholesale production of electrical connection components and gas welding protection devices. Its core product portfolio spans four lines: energy terminal blocks for electricity measuring points (RS, RSB series including multi-output variants and SMG measurement sets), automation terminal blocks including both screw-type (RS series) and spring-type (ORS series) variants, tubular cable lugs and joints in aluminum, copper, and aluminum-copper (per SRPS N.F4.101), and dry fuses plus thermal fuses for gas welding and cutting. Products are manufactured in a 2,000 m² facility powered entirely by solar energy, using imported raw materials including Noryl SEO and Lexan (General Electric) for housings rated for continuous operation at up to 110°C and short-circuit resistance up to 10 kA.

The company's technology centers on proprietary mechanical and electrical designs developed over decades, including multi-output terminal blocks enabling 3-15 meter power supply without traditional busbar distribution, terminal blocks with built-in cylindrical fuses (RSO 16/20 A-D) with LED fault indication, and movable-bridge terminals (RSMS-16) for separation without unscrewing conductors. All products carry ISO 9001:2015, CE, and TUV certifications meeting prescribed world standards.

Sintermetal operates a sales-led wholesale B2B model selling directly to electricity distribution utilities, industrial automation firms, and electrical installation contractors, with dedicated regional sales departments in Belgrade and Central Serbia-South. Distribution beyond Serbia is handled through a general distributor (STD) for Romania, complemented by a multilingual website presence (English, Romanian, Russian, Polish). Pricing is not publicly disclosed and is quoted on a customer-by-customer basis. The company is family-owned under the Nastevski family, with founder Branimir Nastevski succeeded by Bojan Nastevski as Director.

Products and services

• Energy Terminal Blocks (RS, RSB, RNSS series) Line current and voltage terminal blocks for electricity measuring points and distribution cabinets, including single-pole blocks (RS series, 1.5 to 240 mm²), sealable variants (RSB series), multi-output blocks (RS 50/10 to RS 95/10 for powering 3-15 meters), terminal blocks with built-in cylindrical fuses (RSO 16/20 A-D with optional LED indicator), movable-bridge terminals (RSMS-16), and short-circuit busbars (S-type). Houses built from Noryl SEO (GE-Plastic) with Lexan transparency covers, halogen-free and rated for continuous operation at 110°C.
• Set Measurement Groups (SMG-1, SMG-1D, SMG-2) Complete testing sets for semi-indirect and indirect electricity measurement, containing 4 voltage terminals and 3 groups of 3 current terminals. SMG-1 includes fuses with cylindrical fuse housings certified for max 20A load and 10kA short-circuit resistance, with LED indicators for fuse status and DIN 35 mounting. SMG-2 is the variant without fuses. Used by electricity distribution utilities at metering points.
• Automation Terminal Blocks (RS screw-type and ORS spring-type series) Terminal blocks for automation, control, and protection cabinets in industrial machinery and process equipment.
