The R. STAHL Series 8530 residual current circuit breakers (RCCB) are a key component for residual current monitoring, designed to switch off systems in the event of residual currents. They are built for reliable protection of people and equipment, even in hazardous areas. This product line is versatile and suitable for both pulsating direct currents and alternating currents.
Technical Features and Protection
The Series 8530 RCCBs offer crucial fault protection, personal protection, and protection against electrical fires caused by residual currents to earth. The devices are available with various rated operational currents, including 16 A, 25 A, 40 A, or 63 A. They also come with different rated residual currents such as 10 mA, 30 mA, 100 mA, 300 mA, and 500 mA.
The circuit breakers are available in different residual current tripping variants, including A, AS, AP-R, B, BS, B+, and F, as well as an A110 V version. They are designed for an AC rated operational voltage of 230 V and operate at a frequency of 50/60 Hz. The electrical service life is 10, while the mechanical service life is 2 x 10. The enclosure is made from thermoplastic material.
Explosion Protection and International Certifications
A standout feature of the R. STAHL Series 8530 RCCBs is their robust explosion protection, making them suitable for use in hazardous areas. They are certified for use in Zone 21/22 when protected by an Ex tb/tc enclosure. The devices meet stringent international standards, holding both IECEx and ATEX certifications.
IECEx Gas Explosion Protection: Ex db eb IIC Gb
ATEX Gas Explosion Protection: II 2 G Ex db eb IIC Gb
The product is supported by certificates from a number of international bodies, including ATEX (FM), Brazil (ULB), China (COST), and IECEx (FM). This ensures their reliability and compliance for global applications.
Available Product Variants
The Series 8530 RCCBs are available in multiple configurations to suit different installation needs.
1-pole + N: This variant can include auxiliary contacts, such as a 1 change-over contact and a fault signal contact.
3-pole + N: Available with or without auxiliary contacts. The version with auxiliary contacts features a fault signal contact with 1 change-over contact.
The technical data provides detailed information on various specifications, including connection cross-sections. The main connection cross-section ranges from a minimum of 1.5 mm² to a maximum of 25 mm². The auxiliary contact connection cross-section ranges from a minimum of 0.5 mm² to a maximum of 4 mm². The device has a degree of protection of IP2X according to IEC 60529.
Dimensions and Installation
The Series 8530 RCCBs are designed as modular components for easy integration into system solutions. For a 3-pole + N configuration, the dimensions are 169.60 mm (6.68 inches) in height and 110 mm (4.33 inches) in width. The tightening torque for mounting is specified at 2–3 N-m (17.7 to 26.6 lbf-in), and for the auxiliary contact, it is 0.4–0.6 N-m (3.5 to 5.3 lbf-in)
